VizieR Online Data Catalog: gri photometry for 73 stars in NGC419 (Martinez-Vazquez+, 2021)
Abstract
Time-series imaging of NGC419 was obtained with the Gemini Multi-Object Spectrograph (GMOS) mounted at the Gemini-S telescope at Cerro Pachon, Chile. Observations were carried out on the nights of 2017 September 14, 22, and 27 as part of the Fast Turnaround program GS-2017B-FT-2. Observations were obtained with 2x2 binning, resulting in a pixel scale of 0.16pixel/arcsec. Images were obtained in Sloan Digital Sky Survey (SDSS) g, r, and i, with 11, 112, and 7 frames in total and exposure times of 120, 90, and 80s, respectively, reaching a signal-to-noise ratio (S/N) ~50 at the level of the main-sequence turnoff (MSTO).
