VizieR Online Data Catalog: Study of the young open cluster NGC 1960 (Joshi+, 2020)
Abstract
The observations have been carried out with the 104-cm Sampurnanand Telescope (ST) at Manora Peak, Nainital. The ST is equipped with a 2kx2k CCD camera having a field of view of ~13arcminx13arcmin and the pixel scale of 0.758arcsec/pixel in 2x2 pixel binning mode. Further details of telescope and detector can be found in Joshi et al. (2005A&A...433..787J). To carry out the variability study, we monitored NGC 1960 in V band on 43 nights during the period of 2009-2013 spread over four observing seasons where we have accumulated a total of 235 frames.
To carry out detailed photometric study of the cluster NGC 1960, we obtained Johnson-Cousins UBVRI photometry of stars on 2010 November 30 using ST at Nainital. We acquired two frames each in U, B, V, R, and I filters with exposure times of 300, 300, 200, 100, and 60s, respectively. Along with our UBVRI photometric catalogue, we also used many other catalogues where photometric and kinematic data were available for the cluster. We combined our photometric data with Sharma et al. (2006AJ....132.1669S, Cat. J/AJ/132/1669) who provided UBVRI photometric catalogue in the wide field of view (~50arcminx50arcmin) observed through the 105-cm Kiso Schmidt telescope. We also used archival near-IR photometric data from the Two Micron All-Sky Survey (2MASS, Skrutskie et al. 2006AJ....131.1163S, Cat. VII/233) which provides photometry in the J (1.25um), H (1.65um), and Ks (2.17um) filters. And we took data from the Gaia archive DR2 for the proper motion studies (Gaia Collaboration et al. 2018A&A...616A...1G, Cat. I/345). (5 data files).- Publication:
