VizieR Online Data Catalog: NIR light curve of 234 RR Lyrae in Messier 3 (Bhardwaj+, 2020)

Our NIR observations were obtained using the WIRCam instrument mounted on the 3.6m Canada-France-Hawaii Telescope (CFHT) on the summit of Maunakea in Hawaii during four nights between 2019 May 26 and 29. We requested JHKs time-series observations in queue mode centered on the M3 cluster center, and obtained 22 epochs in J and 20 epochs in the H and Ks bands. Each epoch consisted of on average 15 dithered images obtained with an exposure time of 5s per image.
