VII/34C     ESO/Uppsala Survey of the ESO(B) Atlas     (Lauberts 1982)

The ESO/Uppsala Survey of the ESO(B) Atlas Lauberts A. <European Southern Observatory (1982)> =1982ESO...C......0L
ADC_Keywords: Surveys ; Nonstellar objects ; Atlases ; Galaxy catalogs Description: The survey is a joint project undertaken by the European Southern Observatory (ESO) and the Uppsala Observatory to provide a systematic and homogeneous search of the ESO(B) Atlas (also known as the Quick Blue Survey). The ESO(B) Atlas, taken with the ESO 1-m Schmidt telescope at La Silla, Chile, covers 606 fields from -90 to -20 degrees of declination. The fields are similar in size and scale to those of the Palomar Observatory Sky Survey. Unsensitized IIa-O plates and a 2-mm GG385 filter were used to give a passband similar to the Johnson B color. The actual search was conducted at the Uppsala Observatory and resulted in a list of nonstellar objects including all NGC and IC galaxies between -20 and -30 degrees declination, all galaxies down to a limiting diameter of 1.0 arcmin, all disturbed galaxies as faint as possible, all star clusters in the Catalog of Star Clusters and Associations (Alter et al. 1970) and smaller and fainter clusters if recognizable and all planetary nebulae listed in the available catalogs. The catalog includes coordinates, identifications, diameters, position angles, morphological types, classifications, magnitudes, colors, and radial velocities. File Summary:

Historical Notes: * June 1985, by Lee E. Brotzman and Robert S. Hill: The ESO/U catalog was sent to the Astronomical Data Center (ADC), NASA Goddard Space Flight Center, by the Centre de Donnees Stellaires (CDS), in January 1983. This version was equivalent to the book version of the en- tire catalog (Lauberts 1982), having two records per object and a separate notes file. The following changes were made to the catalog format: o The main catalog file was reformatted to have one record per object. o The object classes were placed into a consistent format. o The flags for additional information were segregated each into its own byte in the record. o The notes file was proofread and notes for individual objects were placed in separate records. Programs were written to compare the main catalog file and the notes file, in order to assure that every note had a corresponding note flag in the main catalog, and vice versa. Discrepancies were checked against the lists published in the A. & A. Suppl., against the errata in the A. & A. Suppl., and against the book version. The results of this comparison and other minor corrections were sent to Dr. Andris Lauberts at Uppsala Observatory for confirmation and approval. With his reply, Dr. Lauberts supplied a tape of the then current version of the ESO/U catalog (dated September 9, 1984). This version had four records per object with a record length of 80 bytes, and had the notes incorporated into the catalog record. The new version allowed changes and updates to be made easily with a standard text editor. The processing of this new version was much the same as the previous one: o The main catalog file was reformatted into one record per object. o The object classes were placed into a consistent format. o The notes were placed into a separate file to keep the record length of the main catalog file to a reasonable size. o The programs to compare the catalog with the notes file were run and no discrepancies between these files remain. o The files containing the references to identifications, the references to magnitudes and radial velocities, and the plate data were made from the documentation file on the tape provided by Dr. Lauberts. * 20-Jul-1993, by F. Ochsenbein, CDS: The following few modifications have been made to the original catalogue from the ADC CD-ROM (NASA, 1991) "Selected Astronomical Catalogs Vol. 1": o File "catalog" was transformed from the ADC CD-ROM file nonstell/galaxies/esoupp/esoupp.dat, and - the field e_Bmag/apBmag (mean error on B or aperture) has been transformed into two columns - the flags in columns 147-148 have been put in the right column - the flags in columns 77 and 81 were corrected to : (colon) for the various characters found (e.g. dots, commas, minus), and also for the 3 galaxies 2-G 4, 423-G 9 and 406-G 5 which had a numeric value in column 81 (6, 3 and 1 respectively) - the Hubble class started in column 86 instead of column 90 for 9 objects at positions 023457-3424.0, 085101-3517.2, 132049-4137.6, 052059-2757.1, 071514-2849.6, 075750-2426.0, 095433-3137.7, 105443-3253.3, 224002-3520.0 - values of 0.00 for e_Bmag were transformed to blanks (unknown) o File "plates": records with a value of "60" in RAs or "60.0" in DEm have been corrected (fields 301, 306, 308, 336, 338, 425, 438, 512) o Other remarks: - Many reference codes are included in "refs" file which never appear in the "catalog" file: AA, 1A, 1D, 3A, 3D, 4A, 5A, 5D, 6A, 7A, 9A, 9D, 9F, 9G, 9H, 9J, 9L, 9M. - r_Bmag for 122732-6557.8 is "FW", which was only in "idrefs" file; it has been added to "refs" file - The statistics of the observer code is not consistent with those in "adc.doc" file. The following modifications have been made: "AZA" changed to "AZU" "BAL" and "BSL" changed to "DBA" "DPA" changed to "GPA" The results obtained from the "plates" file are then, if the 6 additional plates are substrated: AZU(1) DBA(73) GPA(184) HES(167) OPA(181) * Documentation file revisited on 25-Oct-1995 * 08-Jul-1998: it was discovered by Ivan Valtchanov that radial velocities larger than 9999 or smaller than -999km/s were truncated to the last four digits. This truncation apparently did not exist in the very original file supplied by A. Lauberts to CDS in 1982, but appears in the 1985 version created at ADC. The 143 velocities concerned where corrected at CDS. Velocities also checked versus Lauberts-Valentijn VII/115 and PGC VII/119, and 122 further corrections on the velocities were performed. Acknowledgments: The authors of the ADC document (Lee E. Brotzman and Robert S. Hill) wish to thank Dr. Lauberts for his assistance in completing the ADC version of the ESO/U catalog. A large fraction of the contents of the "ReadMe" file originates from the "Documentation for the machine-readable version of the ESO/Uppsala Survey of the ESO(B) Atlas", prepared in June 1985 by Lee E. Brotzman and Robert S. Hill at NASA/ADC, document SASC-T-1-5810-5003-85. References: Lauberts, A. 1984, private communication. Holmberg, E. B., Lauberts, A., Schuster, H. -E., West, R.
