Note : this is the description file of the original catalog. This HTML page corresponds well to the original description, but some minor changes in the format may have been introduced in the FITS output files in order to allow for arithmetic operations on quantities such as coordinates and times. h:m:s and d:m:s units are normally converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the units; the value given in the HTML files supersedes the value indicated in the ReadMe file for this catalogue.

    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.

    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 ivan@astro.bas.bg
        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.
