| Contains details of RRLyrae variables defined by the VMC team |
| The catalogue contains fundamental-mode RR Lyrae stars (RRab). All these objects have counterparts in the OGLE-3 catalogue, 11 or more VMC epochs in the Ks-band (hence, the analysis with GRATIS software is possible) and were NOT observed on detector 16. The light curves in the Ks-band were analysed by Fourier fitting with GRapical Analyzer of TImes Series (GRATIS, Clementini G., Di Tomaso S., Di Fabrizio L. et al., 2000, AJ, 120, 2054 ) and using the periods provided by the OGLE III. All available Ks epochs were used in the analysis. Required constraints:
