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.
