Catalog of Infrared Observations, Edition 3.5 Gezari D.Y., Pitts P.S., Schmitz M., Mead J.M. <Unpublished (1996)> Catalog of Infrared Observations, 3rd Edition Gezari D.Y., Schmitz M., Pitts P.S., Mead J.M. <NASA Reference Publication 1294 (1993)>
ADC_Keywords: Infrared sources Description: The Catalog of Infrared Observations and its associated data base comprise a summary of infrared astronomical observations published in the scientific literature from 1965 through 1992 in the wavelength range 1 micrometer - 1 mm. The database contains infrared observational data for sources outside the Solar System, constructed through a search of the most active scientific journals, IR surveys and catalogs. To date, about 5100 journal articles and 10 major survey catalogs have been included in the data base, which contains more than 256000 individual observations of about 11500 different infrared sources. More than 8000 of these sources are identifiable with visible objects. The bibliographical files link observations in the catalog with the original articles published in the literature. References give the standard information plus full titles. The Index of Infrared Source Positions is ordered alphabetically by source name and can be used to quickly locate sources in the position-ordered catalog. For sources with no published IR source position, a nominal position may have been given based on other sources. Nominal positions are usually the best available, but not necessarily the true IR positions. Nominal position references are indicated in the index. File Summary:

Note on catalog.dat: The data base from which the Catalog of Infrared Observations is constructed is maintained at the NASA Goddard Space Flight Center. The Catalog of Infrared Observations has been ordered by increasing right ascension, then declination, then wavelength of the observation. The source name used in the originating papers is given. Thus the same source is often listed under several different names. Sometimes the same source is listed with multiple positions also. Please note the following three points. (1) Sky coverage is not uniform: The catalog data are a mixture of sky surveys, small-scale region surveys, and numerous individual source observations. The whole sky has been surveyed only at a few wavelengths, and then to different levels of sensitivity. Non-survey observations are not spatially homogeneous. (2) Data are presented in original published form: No attempt has been made to create a single system of infrared photometric units, or to eliminate redundant observations. (3) The catalog is as accurate as the published data from which it was constructed: Observations were made by hundreds of investigators, using different instrumental techniques and methods of analysis. Differences Between the Machine-Readable and Printed Versions: Although the printed CIO was produced directly from the Infrared Astronomical Data Base, there are some minor differences between the magnetic tape version and the printed version. These changes were made to clarify the text. The most recent version in print was the 3rd Edition. o Dittos are used in the text only, when information on the previous record is identical with that in the same field for the current record. All data fields in each record of the tape version contain data. o "Nominal" positions (such as the approximate center of a globular cluster) are indicated differently in the printed and tape versions of the data base. In the tape version, the first byte of each record contains an identifier. The first byte does not appear in the printed version of the CIO. o The leading zeros for the hours of right ascension and degrees of declination are explicitly given in the machine-readable copy, whereas they are omitted in the printed version. o The abbreviated IRAS Point Source Catalog flux codes are listed in italics in the printed copy if the flux values given are upper limits. The machine-readable version uses separate flag fields to indicate this condition. A separate file lists the IRAS PSC fluxes. o The position reference, which was included in the 1984 printed version of the catalog, but replaced by the IRAS PSC object name and flux codes in the 1987 and 1992 printed versions, are still present in the machine-readable version of the CIO main data file. o The bibliographic data for a particular reference are given in two files. One file has one entry per record with long record lengths, the other file has entries spread over several records. The spacing, and duplication of the bibliographic reference number at the end of the first line of an entry have been changed. Note on names.dat: The Index of Infrared Source Positions is a listing of infrared sources arranged alphabetically by source name. After locating the name of a source in this index, one can read out its position and then use this information to quickly find the data for the given object in the CIO. When published articles do not include the position of the observed source, the editors provide nominal positions obtained from other data bases. The nominal positions are the best available, but in a few cases do not coincide with the true infrared positions. The source position is given as listed in the CIO at epoch 1950. Sources without published positions appear in alphabetical order with the other names and have blanks in the position field. Note on refs.dat, refa.dat: The Bibliography of Infrared Astronomy links observations in the catalog with the original articles published in the astronomical literature. Approximately 4800 infrared articles and other references are listed in these appendices. The bibliography is arranged chronologically by reference number. It contains the authors names, journal name or document number, volume, page, and full title. The Catalog contains observational data obtained from a search of the following catalogs and scientific journals for the years 1965-1990, inclusive. The number of articles in each journal containing infrared astronomical data and the journal abbreviations used in the bibliography are indicated in the following table.

Soviet Astronomy (Sov. Ast.) Soviet Astronomy Letters (Sov. Ast.

Since plotted spectra cannot be easily included in the current automated data base, this appendix summarizes the wavelength range over which spectra have been published for individual sources. It lists the name, starting and ending wavelengths (in microns), and bibliographic reference number for each published infrared source spectrum. The object name, starting wavelength, and bibliographic reference number are as given in the main catalog. The Atlas is sorted alphabetically by object name with constellation name objects sorted by constellation. The bibliographic reference number refers to the original article via files ref*.dat. Although the inclusion criteria for the Goddard Infrared Astronomical Data Base specifies a wavelength region of from 1 - 1000 microns, some catalog entries have wavelengths outside this range. Wavelengths less than 1 micron indicate that the spectrum starts at this wavelength and extends into the infrared. Note on psc.dat: This file contains data from the Infrared Astronomical Satellite (IRAS) Point Source Catalog (PSC) (Version 2.0) for those sources contained in the Catalog of Infrared Observations. The full PSC name, position and four-band flux data are given. Upper limit values are followed by the suffix "U". Moderate quality fluxes (as defined in the Point Source Catalog) are followed by a colon (:). About 11,500 individual infrared sources represented in this section of the CIO were detected in the IRAS Point Source survey. The IRAS 12, 25, 60, and 100 micron fluxes are listed for these CIO sources. The identification of CIO and PSC sources were based on source identifications made in the IRAS Point Source Catalog, correlated infrared source names, and aliases in the Infrared Source Cross-Index (NASA RP 1182) data base.

Note on name: Object name is left justified. It is common for an astronomical source to be listed by several different names in the catalog, since the observations are presented "as given" by the original authors. In general, source names should be given secondary importance when searching catalog listings, with positions given priority. Source names and positions are cross-referenced in the Index of Infrared Source Positions. Source names are sometimes abbreviated. In some cases the names are augmented by the editors (for example, when the original author assigns the source number but no identifying prefix). Note on RAh,RAm,RAs, DE-,DEd,DEm,DEs: The accuracy of the positional data in the catalog reflects that of the data published by the original author. This is true primarily for visible sources with well-documented positions. In such cases, the "nominal" source position is entered in the position field by the editors. When authors omit specific source positions from their articles, they must presume that the position is common knowledge, to be found in the appropriate standard catalog. When no such position can be obtained by the editors, all such entries are sorted alphabetically by source name and are listed at the end of the catalog. Note on beam: Aperture beam size. The angular beam size of the observation is presented in degrees(D), arcminutes(M), or arcseconds(S). If no beam size information was given in the original reference, a dash(-) is entered. In addition to being a factor in source brightness calculation, beam size can be used as an aid in determining positional coincidences and identifications with other sources, and as a first-order indication of positional accuracy. Note on x_beam: Aperture beam units: S=arcsec; M=arcmin; D=deg; V=mean value; Blank or - = no original beam size given Note on lambda: Wavelength in microns. For spectra the starting wavelength of the spectrum. Catalog entries having the same celestial position are listed in order of increasing wavelength. Thus, a rough spectral distribution appears for each well-observed source position. The units of wavelength given are micrometers (microns). Note that some entries have a wavelength range outside the 1 micron-1 mm range. Wavelengths shorter than 1 micron would indicate that a spectrum exists in the article starting at this wavelength and extending into the infrared. A few observations made at wavelengths greater than 1 mm have been included when the observation was basically done with far-infrared techniques (some broad-band submillimeter observations). The ending wavelengths can be found in Appendix A: file spectra.dat. Note on F(IR): The infrared flux is listed in the same units as published by the original observers. The units have been given one-letter abbreviations (see note x_F(IR) below). Upper limits are flagged in the n_F(IR) field. To protect the integrity of the data base, no attempt has been made to convert these different units or infrared flux into a more homogeneous system. Fortunately, about 95 percent of the flux observations in the catalog have units of "magnitudes" or "Janskys," or have comments such as "polarization data," "spectrum," etc. An additional 3 percent of the entries are in five other commonly used units (B,E,F,I,X). The remaining 2 percent of the entries are in less common units, but which are dimensionally equivalent to one of the more commonly used units. In general, infrared magnitudes are calibrated with respect to the flux density of alpha-Lyr (10,000K BB), which is being defined as 0 magnitude at all infrared wavelengths (see Gillett et al., 1971, Ap.J., 164, 83; Gertz and Woolf, 1971, Ap.J., 165, 185) . The following symbols sometimes occur in the comments to the IR flux field (n_F(IR)): V=variable or mean of several values, L=lower limit (detector saturated), E=editors determined flux from maps, spectra, or other material in the article presented in non-tabular form. When spectral data (S) are listed (see x_F(IR)), only the starting wavelength of the spectrum is given in the "lambda" column. Starting and ending wavelength of published spectra are given in the Atlas of Infrared Spectral Ranges. Note on x_F(IR): Infrared flux unit code. A = normalized magnitude B = 10-19W/m2/Hz/sr C = magnitude derived from color D = diameter measurement E = erg/s/cm2/sr F = 10-16W/cm2/um G = 10-14erg/s/cm2 H = log(ergs/s/cm2/Hz) I = 10-9W/cm2/um/sr J = Jy K = log(Jy) L = log(W/m2/Hz) M = magnitude N = log(erg/s/cm2/um) O = magnitudes/arcsec2 P = polarization data Q = log(10-3Jy) R = log(W/cm-2/um) S = spectral data T = -2.5log(erg/s/cm2/Hz)-48.60 U = upper limit V = variable W = 10-14W/m2 X = 10-18W/cm2 Y = relative line intensity Z = 10-21W/cm2/um/arcsec Note on n_F(IR): Comments to F(IR), the infrared flux. E = Flux obtained by the editors L = Flux value is a lower limit U = Flux value is an upper limit V = Flux value is an average value ? = Flux value as published is inconsistent Blank = no comment Note on r_F(IR): The bibliographic reference number identifies the original Journal article for each observation in the catalog, keyed to the entry in the bibliographic reference file. The bibliographic reference number is made up of the year and month of publication, and a randomly assigned sequential number. In case the publication did not contain infrared observations an "89" or "99" was assigned as the month of publication. A "89" means that the reference was published in the nineteenth century. References that do not indicate the month of publication have 00 in the month field. Note on IRASname: IRAS cross identification based on IRAS Point Source catalog V2.0 identifications. Only object ID was checked - not position. Cross- references are up-to-date through 1990. Records for which PSC cross-references have not been checked are flagged with a ? in byte 63. Note on 12um, 25um, 60um, 100um: IRAS flux strength code. The strength code is logarithmic as follows: 0 = 0.5-5 Jy; 1= 5-50 Jy; 2=50-500 Jy; 3 = 500-5000 Jy; 4 = 5000-50000 Jy. For each CIO source detected by IRAS, the corresponding order-of-magnitude IRAS PSC version 1.0 flux is given using four digits, one each for the four IRAS bands. The values represent the approximate logarithm of the flux density. This allows the user to get an immediate estimate of the IRAS PSC fluxes in a compact format. Note on q_12um, q_25um, q_60um, q_100um: IRAS Flux Quality Codes: Blank=good quality; :=moderate quality; S=Saturated; U=upper limit.
