From the Bochum Galactic Disk Survey, time series have been obtained in the
r and i bands on an (up to) nightly basis. Depending on the field, the time
series contain up to more than 300 nights over more than 7 years. Each
measurement represents the averaged flux over 10 minutes of observation
(from 9 averaged 10s images).

The Bochum Galactic Disk Survey is an ongoing 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 since mid-2010 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 more than seven
years. Additionally, intermittent measurements in Johnson UVB and Sloan z
have been recorded as well.</description><table><name>bgds.phot_all</name><description> All mean photometry of bgds in one table. It may be simpler to write
