|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 mags/arcsec2.

The calibrated, masked/median-binned (9x9) surface
brightness maps are available here:
Full resolution survey mosaics are available here.
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) +
Note (1/2/20): Prior to
this note, the photometric solution given on this page and
written into the image header contained a sign error in the
color term. This does not affect the data (or any published
results), since the proper calibration was always being
applied. It was simply a typo on this page and in what was
written to the image headers. If you downloaded the data
prior to this date, you should re-download the images so
that you have versions with the correct solution written in
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.
