II/275              IRAS Faint Source Reject Catalog          (IPAC 1992)

IRAS Faint Source Reject Catalog, Version 2.0 (1992 July) Moshir M., Kopan G., Conrow T., Hacking P., Gregorich D., Rohrbach G., Melnyk M., Rice W., Fullmer L., White J., Chester T. <Explanatory Supplement to the IRAS Faint Source Survey, Version 2, JPL D-10015 8/92, Infrared Processing and Analysis Center (IPAC), California Institute of Technology (1982)> =2008yCat.2275....0M
ADC_Keywords: Photometry, infrared ; Infrared sources ; Surveys Mission_Name: IRAS Description: The Faint Source Reject Catalog contains 593,516 sources rejected for inclusion in the Faint Source Catalog (Cat. II/156) because they failed to meet one or more of the criteria established to ensure the reliability of the FSC. The REJECTED sources in the FSR are either in confused regions of the sky, or in areas with |b|<10-20°, or were detected only in a single band with a signal-to-noise ratio of 3-6. The FSR also includes sources from areas of the sky covered by fewer than six detector passes, and sources contaminated by or caused by cometary debris trails. The files described here contain selected columns from the original Faint Source Reject IRAS catalogue; the full set is available as a ascii FITS table. In the descriptions below, the original names of the columns are added at the end of the explanations of each column. File Summary:

Note (1): IRAS name starts by F (Faint source catalog, see Cat. II/256) or Z (rejected) Note (2): values set to 0 or blank signify no detection in that particular wavelength band; locSNR values sometimes have the value 0.0, distinct from blank, when there were too few observations in the pixel containing the peak signal to estimate the noise there. Note (3): The term 'cold' used in the three cirrus flags means 100 mu-only, or source having the color index log(Fν(60µ)/Fν(100µ)) ≤ -0.75. Note (4): 3=high quality, 2=moderate quality, 1=upper limit Note (5): Non-color corrected flux density Note (6): Non-linear flux density correction

Global Notes: Note (G1): Type ranges from 1 to 15 and states whether an association was found in: * a stellar catalogue (1=bit#0) * an extragalactic catalog (2=bit#1) * catalogs with other types of objects (4=bit#2) * in a catalog with mixed types (8=bit#3) For example, if associations were found to both an extragalactic catalog and a stellar catalog, Type has a value of 3 (1+2)
History: The file was created from the original FSR_LONG.DATA FITS file, extracting the columns (fields) mentioned in the the fields 1,2,17,18,21-52,79-99,196-205,230-238,256,267,268,319,325,326 only were kept.
