Description:
The Interim Supplement to the General Catalogue of Stellar Radial
Velocities (Evans 1979, ISGCRV) contains radial velocities for stars
with right ascensions from O through 20 hours. The ISGCRV is intended
as a continuation of the General Catalogue of Stellar Radial
Velocities (Wilson 1953, GCRV). The ISGCRV resulted from a literature
search and data reduction by D. S. Evans covering approximately the
years 1951-1977. It contains adopted velocities on the Mount Wilson
system. Unfortunately, the individual mea- surements and the
literature references could not be included in this version. Both for
this reason, and because the ISGCRV covers only O through 20 hours of
right ascension (equinox 1900), the ISGCRV should be used with the
Bibliography of Stellar Radial Velocities (Abt and Biggs 1972), or the
Bibliographical Star Index Retrieval System (Hill et al. 1984).

Note on ID:
Name of star (Henry Draper number when available). Some H II regions
and planetary nebulae are also included.
Note on n_Mag1:
A letter (A, B or C) signifying a component of a multiple system,
a left parenthesis, (, for non-photoelectric visual magnitudes,
or an asterisk (*) for Henry Draper magnitudes.
Note on Mag1:
For one star, HD 16157, this value is given as var? in the proof
copy; in this version, 99.99 is used instead.
Note on n_Mag2:
letters signifying components of multiple system,
the letter V (unexplained meaning, exists only for HD 23793A (suspected
variable) and HD 24534 (variable X Per))
the colon (:) for approximate (applies to Mag1)
the plus (+) for greater than (applies to Mag1)
Note on Mag2:
Implies a multiple system. The comment fields specify the components.
Note on n_Mag3:
Letter signifying a component of multiple system to which Mag3 applies.
Note on Mag3:
Implies a multiple system. The comment fields specify the components.
Note on SpType:
Given in the customary form, except that upper-case letters are
substituted for lower-case. The main spectral type is always in byte 58,
leaving room in bytes 56-57 for Mount Wilson luminosity classes, such as
SD and C. An asterisk (*) in byte 58 signifies an H II region or
planetary nebula, according to the notation accompanying it.
Note on RVel:
Adopted radial velocity in the system of the GCRV. A value of 9999.9
indicates that no velocity was given in the proof copy.
Note on u_RVel:
Colon (:) for approximation; or right parenthesis ")" for parentheses
in the proof copy, which appear to indicate a question about the
identity or type of the object to which the velocity applies.
In one case, HD 196877, this byte contains a 9, which is the hundredths'
digit of the velocity, and in another case, BD +40 4220 (suspected
spectroscopic binary), this byte contains an *.
This field can also be blank.
Note on q_RVel:
A rating from A through E, in the system of the GCRV.
The rating itself will always be in byte 87, if given.
Byte 88 can contain a question mark (?) or blank.
A number of velocities were not assigned a quality rating.
In two cases (HD 74712 and 195647), a value of "3" was assigned.
Note on Nplates:
Total number of plates measured for all the velocities used to
arrive at the adopted velocity.
Note on u_Nplates:
Comment on plate count. Can be a question mark (?),
a plus (+) meaning greater than, or blank.
Note on ObsCode:
Abbreviations for observatories (or observers), separated by commas.
Note on GCRV:
Catalog number given for the star by Wilson (1953, catalog <III/21>)
Note on Flags:
Letter V (byte 110) for variable velocity, or else blank.
Letter M (byte 111) for known variable magnitude, or else blank.
Letter D (byte 112) for double or multiple star, or else blank.

Historical notes:
Other versions of the ISGCRV
have been distributed, but this one supersedes them, as it was
corrected from a set of proof copies supplied by Evans, which
included corrections and additions by several referees. Xeroxes of
Evans's data file containing the results of the literature search
were also available to us.
Remarks and Modifications:
The Astronomical Data Center (ADC), NASA Goddard Space Flight Center,
received the Interim Supplement to the General Catalogue of Stellar Radial
Velocities on magnetic tape from the Centre de Donnees Stellaires,
Strasbourg, France, in 1981. That version contained 80-byte card images.
Different parts of the catalog had been keypunched at different sites, so
that there was variation not only in the format, but also in the kinds of
data fields included. For example, some sections included catalog numbers
from the GCRV, and some did not. Also, an attempt had been made to code
spectra in a condensed format, but consistency and completeness were not
achieved.
The modifications to this version comprised several steps:
1. The three parts of the catalog were merged in a uniform format. A
sequential number was assigned to each record. For clarity, different
kinds of names were temporarily assigned to different fields.
2. The resulting file was proofread against the proof copies from Evans.
At this stage, it turned out that not all the proof copies were
identical. Evans had sent some of them to various radial velocity
specialists for review. Some of the keypunching in France was done
from the resulting revised version, and some was not.
3. The corrections, coded by the proofreader on 80-column forms, were
themselves keypunched and proofread.
4. Now it was necessary to adopt a consistent policy on the revisions
made by referees. It was decided to incorporate new photometry
without comment, since these data are not primary. Velocities from the
referees have also been included, but are listed in Figure 3 on page
8. The proofreader's corrections were amended in accordance with this
policy, after a re-examination of all the proof copies.
5. A Fortran program was used to apply the amended list of proofreader's
corrections to the catalog.
6. A Snobol program was used to convert the spectra to a conventional
format. This program was partly interactive, in that it required
real-time intervention either to confirm the program's modification,
or to supply a substitute for that modification. The catalog was
split into eight parts for this program. The output files were then
merged again.
7. During the preceding steps, a list of special problems had been
maintained. These difficulties were now resolved. Several corrections
were made with an interactive text editor, and a number of omitted
records were inserted in the same way.
8. Again by means of a text editor, GCRV numbers (previously given in
only part of the machine-readable version) were added.
9. Many records in the machine-readable version as received had asterisks
that seemed in most cases to denote double stars. The source of this
information was the proof copies of the ISGCRV notes from Evans (not
part of the current catalog). But these notes seemed to have been
misinterpreted so frequently by the original keypunchers that in
several parts of the catalog, the asterisk meant, in practice, no more
than unusual star. The notes were re-examined, and the flags in bytes
111-113 were substituted for the asterisks.
10. Blank fields and sequential line numbers were deleted, and the name
fields were merged. The present 114-byte record resulted.
11. An ADC utility program was run to check for invalid numerical values.
A few corrections were made with a text editor.
The known referees consulted by Evans on this catalog are the following:
D. Crampton, J. Elliott, C. Fehrenbach, W. Gliese. It is not certain that
this list is complete. The source for these names is the notations on the
proof copies that were available to us. The referee who gave each
individual velocity in Figure 3 (below) had to be guessed from handwriting.
Every name in that list is uncertain to some extent. Moreover, it is evident
that none of the referees reviewed the entire catalog. In any case,
the referees should not be held responsible for any of the catalog's
contents, although we acknowledge their work and hope that we have made good
use of it.
The adopted velocities, except for the few listed in Figure 3(below), are
due entirely to Evans. The responsibility of the authors of this document
is limited to transcription and, sometimes, interpretation. We made no
effort to evaluate or amend the adopted velocities--only to produce a good
machine-readable version of the results as they were available to us. We
lament our inability to produce a good scientific introduction to the
ISGCRV, but such an endeavor would have exceeded both our time and our
expertise.

* ADC update July 1995: The documentation was converted to standard form.
During verification some errors were found. The following 2 changes
should be noted: In record 4098 the Mag1 value was changed from "10. 0"
to "10.09". In record 6814 the plate count value was aligned "4 "
to " 4". The original records could not be consulted for these changes.
* CDS update October 1996: a few misaligned values for the number of
plates (Nplates) in records 1213, 3254, 3758, 4503, 5065, 5363, 7028.
