VizieR Online Data Catalog: PHAT. XIII. M31 Cepheid P-L relation (Wagner-Kaiser+, 2015)

The data used in this paper are obtained from the PHAT photometry of M31. The PHAT survey coverage, design, and photometry are described at length in Dalcanton et al. (2012ApJS..200...18D). The observations utilize the Wide Field Camera 3 (WFC3) in both the ultraviolet-visible (UVIS) mode and the infrared (IR) mode and the Advanced Camera for Surveys (ACS) Wide Field Channel (WFC). They cover about one third of the disc of M31 across six filters (F275W and F336W in the UV with WFC3; F110W and F160W in the IR with WFC3; F475W and F814W in the visual bands with ACS). Each HST pointing is two orbits: one orbit for WFC3/UVIS and one orbit for WFC3/IR (with ACS/WFC in parallel mode). The coverage of M31 by PHAT is divided into 23 'bricks', each composed of 18 HST fields of view (in a 6x3 layout, each brick covering a 3x1.5kpc area).

To obtain the largest sample of Cepheid observations possible, we use multiple Cepheid catalogues: PAndromeda (Kodric et al. 2013, Cat. J/AJ/145/106), DIRECT (Kaluzny et al. 1998, Cat. J/AJ/115/1016; 1999, Cat. J/AJ/118/346; Stanek et al. 1998, Cat. J/AJ/115/1894; 1999, Cat. J/AJ/117/2810; Bonanos et al. 2003, Cat. J/AJ/126/175), and Cepheids already identified in the PHAT images (Riess et al. 2012, Cat. J/ApJ/745/156).
