Data on RR Lyrae Variables

Photometry

The following is photometry I've been given, or found in the literature. It is by no means complete... just what comes across my path in the course of research, or is sent to me by gracious people like yourself. If you have any RR Lyrae data you would like to include here, please email me at layden(at)bgsu(dot)edu.

• Field Stars: 35 stars kindly provided by Marcio Catelan (1998, ApJ, 495, L81), Readme.
• Field Stars: Walraven photometry by Jan Lub (1977, A&AS, 29, 345), Readme.
• M5: BV photometry of 45 RRL (Brocato et al. 1996, AJ, 111, 809; and Caputo et al. 1999, MNRAS, 306,815).
• M22: all RRL in a tar.gz file (UBVI; Kunder et al. 2013, A,J 146, 119).
• M68: sample data file, all 47 stars in one gzipped tar file (Walker, A.R. 1994, AJ, 108, 555).
• NGC 6171: sample data file, all stars in a single tar file (Clement & Shelton 1997)
• IC 4499: sample data file, all stars in a single tar file (Walker, A.R. 1996, AJ, 112, 2026).
