VizieR Online Data Catalog: Properties of 70 RR Lyrae stars in the LMC bar (Muraveva+, 2015)
Abstract
In order to derive mean Ks magnitudes for the RR Lyrae stars sample we used data from the VMC survey (Cioni et al. 2011A&A...527A.116C). Started in 2009, the VMC survey covers a total area of 116 deg2 in the LMC with 68 contiguous tiles. The survey is obtaining YJKs photometry. The Ks-band photometry is taken in time-series mode over 12 (or more) separate epochs and each single epoch reaches a limiting Ks magnitude ~19.3 mag with a signal-to-noise ratio (S/N) ~5 (see Figure 1 of Moretti et al. 2014, J/MNRAS/437/2702). On the bright side, VMC is limited by saturation at Ks~11.4 mag. The majority of RR Lyrae stars in our sample are located within the VMC tile LMC 5_5. Observations of the tile LMC 5_5 were performed in 15 epochs taken in the period from 2010 October 30, to 2012 January 11.
