3047B III/47B Stellar Radial Velocities 0-20 hrs D S Evans IAU Symp. 30 57 1967 1967IAUS...30...57E Radial velocities 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).

ID Star id Name of star (Henry Draper number when available). Some H II regions and planetary nebulae are also included. --- RAh Right ascension, equinox 1900 (hours) h RAm RA minutes min RAflag RA approx flag Colon (:) signifying approximation --- DE- Dec sign --- DEd Declination, equinox 1900 (degrees) deg DEm Dec arcminutes arcmin DEflag Dec approx flag --- ComA Note on magnitudes A letter signifying a component of a multiple system, a left parenthesis, (, for non-photoelectric visual magnitudes, or an asterisk (*) for Henry Draper magnitudes. This comment applies to magnitude 1. --- Mag1 Magnitude (V) 1 For one star, HD 16157, this value is given as var? in the proof copy; in this version, 99.99 is used instead. mag ComB Second note on magnitudes Letters signifying components of multiple system, the letter V (unknown meaning), colon (:) for approximate, or plus (+) for greater than. The colon and plus apply to magnitude 1, and the other notations apply to magnitude 2. --- Mag2 Magnitude (V) 2 Implies a multiple system. The comment fields specify the components. mag n_Mag3 Component to which Mag3 applies --- Mag3 Magnitude (V) 3 Implies a multiple system. The comment fields specify the components. mag Spect Spectrum Given in the customary form. 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. --- Vel Velocity km/s VelCom Vel comment 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. This field can also be blank. --- Quality Quality 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. --- Pcnt Plate count Total number of plates measured for all the velocities used to arrive at the adopted velocity. --- PcntCom P count comment Comment on plate count. Can be a question mark (?), a plus (+) meaning greater than, or blank. --- ObsCode Observe Code Abbreviations for observatories (or observers), separated by commas. --- GCRVnum GCRV number Catalog number given for the star by Wilson (1953) --- flag1 Var vel flag Var vel flag. Letter V for variable velocity, or else blank. --- flag2 Var mag flag Var mag flag. Letter M for known variable, or else blank. --- flag3 Multiple flag Multiple flag. Letter D for double or multiple star, or else blank. --- C.-H. Joseph Lyu Hughes STX/NASA 1995Jun22 UNKNOWN UNKNOWN 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. UNKNOWN UNKNOWN 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. Figure 3. Referees' Velocities Star R.A.
