Description:
We present a catalog of RR Lyrae stars distributed across ∼14000deg2
of the sky from the combined data of the Sloan Digital Sky Survey
(SDSS, http://www.sdss.org), the Panoramic Survey Telescope and Rapid
Response System 1 (PS1, Kaiser et al., 2002, SPIE, 4836, 154), and the
second photometric catalogue from the Catalina Survey (CS2,
http://nesssi.cacr.caltech.edu/DataRelease), out of these, ∼2021 RRL
stars (∼572 RRab and 1449 RRc) are new discoveries. The RRL stars have
heliocentric distances in the 4-28kpc distance range. Our catalog has
a completeness level of ∼50 per cent for both RRab and RRc stars, and
an efficiency of ∼99 and ∼87 per cent for RRab and RRc stars,
respectively. We provide the positions, CSDR2 mean magnitudes, CSDR2
amplitudes, subtypes, periods, ephemeris, and the heliocentric
distances of our RRab and RRc stars.
