The Burrell Schmidt Deep Virgo Survey



Over the course of 7 observing seasons spanning the years 2004-2011, we used CWRU Astronomy's Burrell Schmidt telescope at Kitt Peak National Observatory to conduct a deep, wide-field imaging survey of the nearby Virgo Cluster of galaxies. The survey footprint covers 16.7 square degrees in the Washington M filter and 15.3 square degrees in a modified Johnson B filter ("Bdsp"), with 11.1 square degrees covered in both filters. The data is transformed into standard Johnson B and V magnitudes, and we achieve a limiting 3-sigma surface brightness of mu(B)=29.5 and mu(V)=28.5.

The calibrated, masked/median-binned (9x9) surface brightness maps are available here:
Full resolution survey mosaics are available here. Please note these are very large fits files!

The photometric solution for the images (already applied to the masked/median-binned images) is given by:

mB = -2.5log(IB) + 0.125(B-V) + 28.973
mV = -2.5log(IM) + 0.246(B-V) + 28.606


If you use the imaging data in your research, please cite the main survey paper (Mihos et al 2017), and please also let us know how you're using the data. Thanks.
