VizieR Online Data Catalog: CCD observations in BVRI bands for TY Pup (Sarotsakulchai+, 2018)

The first set of light curves of TY Pup in BV(RI)_C bands were c out for several nights from 2015 January to February with the back illuminated Apogee F42 2048x2048 CCD attached to the 0.6 m Cassegrain reflecting telescope of PROMPT-8 robotic telescope. The telescope is located at the Cerro Tololo Inter-American Observatory (CTIO) in Chile. The web-based SKYNET client allowed us to request and retrieve image remotely via the internet. SKYNET system also provided nightly calibration images, including bias, dark, and flat-field images (Layden & Broderick 2010PASP..122.1000L). All CCD reductions and aperture photometry measurements were done with standard procedure packages of IRAF. The second set of light curves were obtained from 2017 March to April. To obtain more times of light minimum, TY Pup was also monitored by using the 60 cm and 1.0 m telescopes of Yunnan Observatories (YNOs) in 2015 February and 2018 January, respectively. These telescopes were equipped with a Cassegrain-focus multicolor CCD photometer where an Andor DW436 2 K CCD camera. Standard Johnson-Cousin-Bessel BV(RI)_C filters were used.
