We provide mean photometry in U, B, V, z, r, and i bands. Note that sources in different bands are not matched. Also, sources sitting in the regions imaged in multiple fields have not been matched even within one band. In i and r, BGDS light curves are available.

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.bgds.phot_all All mean photometry of bgds in one table. It may be simpler to write queries against the split-band tables phot_band. Measurements in different fields and bands have not been merged, as that procedure is too error-prone in crowded milky way regions.band_nameThe band the mean photometry is given for.meta.id;instr.filtercharnullableobs_idMain identifier of this observation (a single object may have multiple observations in different bands and fields)meta.id;meta.maincharnullableraICRS right ascension for this object.pos.eq.ra;meta.maindoublenullabledecICRS declination for this object.pos.eq.dec;meta.maindoublenullablemean_magMean magnitude in band given in phot_band.magphot.mag;stat.meanfloatnullableerr_magError in mean magnitude in this bandmagstat.error;phot.magfloatnullableampDifference between brightest and weakest observation.magphot.mag;arith.difffloatnullablefluxMean flux in this band; this is computed from the mean magnitude based on Landolt standard stars.mJyphot.flux;stat.meanfloatnullableerr_fluxError in mean flux in this bandmJystat.error;phot.fluxfloatnullablenobsNumber of observations in this light curvemeta.number;obsshort
