COMMISSIONS 27 AND 42 OF THE IAU INFORMATION BULLETIN ON VARIABLE STARS Number 3995 Konkoly Observatory Budapest 21 February 1994 HU ISSN 0374 - 0676 VARIABLE STARS OBSERVED IN THE CARNEGIE SOUTHERN HEMISPHERE OBJECTIVE-PRISM SURVEY In 1977 S. A. Shectman and G. W. Preston began an objective-prism survey designed to discover stars of low metal abundance in the galactic halo by making photographic observations of a relatively small region of the spectrum centered on the H and K lines. Originally the 46-cm Palomar Schmidt was used, but soon the work was transferred to the 61-cm Curtis Schmidt on Cerro Tololo. In the ensuing years a very large number of weak-metal candidates and probable horizontal-branch A stars have been picked up, for many of which accurate position, photometry, and additional spectroscopy were obtained. It seems likely that an appreciable number of known RR Lyrae stars would have been noted in this work, but the investigators did not, at least at first, check their lists for such. The writer has done so; and a considerable number of known RR Lyrae and suspected variables are in fact included in their lists. The objects involved are contained in Table 1, where the numbers given after the plate numbers refer to the following papers: 1. Pier, J. R., 1982, AJ, 87, 1515 [BIBCODE 1982AJ.....87.1515P ] 2.
