Description:
A uvbyHβ Stromgren photometric survey covering 16sq.deg in the
anticenter direction was carried out using the Wide Field Camera (WFC)
at the Isaac Newton Telescope (INT), with a typical seeing of 1-1.5".
Data from three different observing runs (2009A, 2010B, 2011A) were
used for the catalog.
The calibration to the standard system was undertaken using open
clusters. A main catalog of 35974 stars with all Stromgren indexes,
and a more extended one with 96980 stars with partial data. The
central 8sq.deg have a limiting magnitude of V=17mag while the outer
region reaches V=15.5mag.
Two catalogs are available, the first one with the final mean values
and a second one with all the individual measurements for each star.
Remarks about the Hβ calibration (2013-06-14):
While computing the physical parameters for the stars in the catalog,
some small biases in the Hβ values were detected. The calibrations
are being re-checked, so if you plan to use these data, please contact
us (email below)
