History:
The machine-readable catalog was prepared by Dr. R. Kraan-Korteweg
of the Astronomisches Institut der Univ. Basel, who graciously
supplied it on magnetic tape to Ms. Lynn S. Fischer of the Jet
Propulsion Laboratory to be used for the IRAS project. Ms. Fischer
kindly supplied it to the Astronomical Data Center (ADC). The
machine version was supplied "as is" to Dr. Herbert J. Rood of the
Institute for Advanced Study, who checked certain data fields
against the published catalog and made suggestions for improvement
of the computer version.
Modifications made at the ADC include the correction of several
errors noted by Dr. Rood, the right justification and alignment of
all galaxy designations, the removal of decimal points from some
RA values to allow uniform computer processing, and the expansion
of the field containing the mean error of the observed velocities
to allow for fractional values (these had been rounded) plus the
insertion of the correct values. Zero values in the A(i) field
were changed to 0.00 so that the field can be read with an F
format (there are blank fields also) and the velocity field was
expanded so that signs could be moved to occur uniformly in byte
66; "+" signs were added to positive values.
A brief description of the data fields in the machine version of
the catalog follows. The description has been prepared at the ADC
using a handwritten description from Dr. Krann-Korteweg and the
data description given in the published catalog (see the latter
for more detailed descriptions and comments). This description is
brief and almost certainly not complete, since it was assembled
from available information without a thorough comparison of the
machine version with the published catalog. Any codes not
described in the table should be interpreted by comparison with
the published catalog. A few coding errors were found and
corrected at the ADC during the course of this work, but a
complete check has not been made; thus, the ADC takes no
responsibility for any errors found.
This "ReadMe" file was later standardized at CDS.
