VizieR Online Data Catalog: VMC survey. XXVI. SMC RR Lyrae stars (Muraveva+, 2018)

VMC (Cioni et al., 2011A&A...527A.116C, Cat. II/351) is an ongoing imaging survey of the MS in the Y, J, Ks passbands, centred at λ=1.02, 1.25 and 2.15um, respectively. It started in 2009 and observations of the MS were 89 per cent complete as of 2017 September, while the observations of the SMC were 100 per cent complete. The survey covers the LMC area (~105deg²) with 68 tiles, the SMC (~42deg²) with 27 tiles, the MB area (~21deg²) with 13 tiles and part of the Stream (~3deg²) with two tiles. The VMC Ks-band observations are taken over 13 separate epochs: 11 times with an exposure time of 750s (deep epochs) and twice with an exposure time of 375s (shallow epochs). Additional epochs may be obtained if observations have to be repeated because the requested sky conditions are not met.
