Depending on the field, the time series contain up to more than 300 nights over 9 years. Each measurement in r and i represents the averaged flux over 10 minutes of observation (from 9 averaged 10s images). Additionally, intermittent measurements in Johnson UVB, Sloan z and the narrowbands OIII, NB, Halpha and SII have been recorded as well. The Bochum Galactic Disk Survey is a project to monitor the stellar content of the Galactic disk in a 6 degree wide stripe centered on the Galactic plane. The data has been recorded from September 2010 to September 2019 in Sloan r and i simultaneously with the Robotic Bochum Twin Telescope (RoBoTT) at the Universitaetssternwarte Bochum near Cerro Armazones in the Chilean Atacama desert. It contains measurements of about 2x10^7 stars over nine years. The source images are available from ivo://org.gavo.dc/bgds/q/sia.bgds2.matched Median photometry in U, B, V, z, r, and i broadbands as well as the narrow bands OIII, NB, Halpha and SII for particular objects; all measurements have been matched to the nearest Gaia DR3 object.
