Region file centered at (228.79863,+44.42859).
which is (15:15:11.67, +44:25:42.9)
Made source region file with 5" aper with name uvot_flux_src5.reg
Coincidence losses are calculated using a 5" aperture.
Exposure times (t_exp) have NOT been corrected for coinc. loss, but rates and mags have been.
A table entry starting with # is an exposure with no aspect solution.
A table entry starting with ! has no pixels in either source or background region.
UL in table gives the 3 sigma upper limit for detection using only the rate in the background region.
UL in the Sum gives the 0.9987 upper limit for detection taking the observed counts into account.
weighted rates (wtd_rate) combine results from different exposures using optimal weights appropriate
for a weak source producing the same magnitude in each filter.
The weight for an exposure is the expected number of source counts divided by the background rate.
The rate is normalized so that a 20th mag. source produces 1 cps.
