VizieR Online Data Catalog: Variability in protoplanetary nebulae. VII. 5 LCs (Hrivnak+, 2020)
Abstract
Most of the observations were carried out at the Valparaiso University Observatory (VUO) with the 0.4m telescope and SBIG 6303 CCD camera. Observations began in 2008 and were carried out through 2017 or 2018, depending upon the object. These were complemented by observations made with two telescopes operated by the Southeastern Association for Research in Astronomy (SARA). They are the 0.9m at Kitt Peak National Observatory (SARA-KP) and the 0.6m Lowell telescope at Cerro-Tololo Interamerican Observatory (SARA-CT). The SARA observations began in 2009 or 2010 and continued through 2016 or 2018, depending upon the object. Standard Johnson V and Cousins RC filters were used with each of the telescope-detector systems.
