The USNO-A1.0 comparison looks promising for temporary use, but I do
worry about the occasional "ringers" that are 0.3-0.5 mag. in error compared
to the Henden photometry.
Michael Richmond will chime in here I'm sure about the TASS data,
but at present they are running with V and I filters (a good combination
from an astrophysical standpoint), but may add others in future systems.
They've already got reasonably good photometry for over 100,000 stars along
the Equator down to about V mag. 12-13.
