J/A+A/442/381  Precise positions of RR Lyrae Stars with Vmax>12.5 (Maintz, 2005)

Proper identification of RR Lyrae Stars brighter than 12.5 mag. Maintz G. <Astron. Astrophys. 442, 381 (2005)> =2005A&A...442..381M
ADC_Keywords: Positional data ; Stars, variable ; Cross identifications Keywords: astrometry - stars: variables: RR Lyrae - catalogs Abstract: RR Lyrae stars are of great importance for investigations of Galactic structure. However, a complete compendium of all RR-Lyraes in the solar neighbourhood with accurate classifications and coordinates does not exist to this day. Here we present a catalogue of 561 local RR-Lyrae stars (Vmax≥12.5mag) according to the magnitudes given in the Combined General Catalogue of Variable Stars (GCVS) and 16 fainter ones. The Tycho2 catalogue contains ∼100 RR Lyr stars. However, many objects have inaccurate coordinates in the GCVS, the primary source of variable star information, so that a reliable cross-identification is difficult. We identified RR Lyrae from both catalogues based on an intensive literature search. In dubious cases we carried out photometry of fields to identify the variable. Mennessier & Colome (2002, Cat. J/A+A/390/173) have published a paper with Tyc2-GCVS identifications, but we found that many of their identifications are wrong. File Summary:
