VizieR Online Data Catalog: VR photometry for 914 stars in NGC 188 (Chen+, 2016)

We observed the open cluster NGC188 for a total of 36 nights during two separate periods (2014 September 28-October 7: 2014 Sep 28, 2014 Oct 01, 2014 Oct 02, 2014 Oct 04, 2014 Oct 05, 2014 Oct 07; and 2016 January 13-March 10: 2016 Jan 13, 2016 Jan 14, 2016 Jan 15, 2016 Jan 20, 2016 Jan 22, 2016 Jan 23, 2016 Jan 25, 2016 Jan 26, 2016 Jan 27, 2016 Jan 28, 2016 Jan 29, 2016 Jan 30, 2016 Feb 02, 2016 Feb 03, 2016 Feb 04, 2016 Feb 05, 2016 Feb 06, 2016 Feb 07, 2016 Feb 09, 2016 Feb 14, 2016 Feb 17, 2016 Feb 19, 2016 Feb 22, 2016 Feb 24, 2016 Feb 25, 2016 Feb 27, 2016 Feb 28, 2016 Feb 29, 2016 Mar 05, 2016 Mar 07) using the 50cm Binocular Network telescope (50BiN) at the Qinghai Station of Purple Mountain Observatory (Chinese Academy of Sciences). The time-series light-curve observations in the Johnson V and R bands were obtained simultaneously using two Andor 2k*2k CCDs. The telescope's field of view is 20*20arcmin², which is adequate for covering the central region of NGC188.
