Could not find/read custom source region custom_1033328_src.reg
Used archived BAT position of 47.31792 35.32192
Reference: GCN_Circulars-29537-Thu,_18_Feb_2021_21:02:10_-0500
The position is (03:09:16.30, +35:19:18.9)
Using source region:

fk5;circle(47.31792,35.32192,3") # color=red dash=0
Source region spec. is: 47.31792 35.32192 3"
Region file centered at (47.31792,35.32192), which is (03:09:16.30, +35:19:18.9)
Could not find/read custom background region custom_1033328_bkg.reg
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.
The no. of background pixels has been corrected by the ratio of coincidence loss corrections in the source and background regions.
The errors have been adjusted to account for the binomial distribution of counts at large rates.
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.
A table entry starting with % is unreliable because it is not well inside the image.
Upper limits in tables give the 0.9987 confidence limit using Bayesian analysis for detection taking the observed counts into account.
Upper limits in plots give the 0.9772 confidence limit using Bayesian analysis.
Weighted rates in tables (wtd_rate) combine rates from different exposures weighted by the expected source rate divided by the background rate
The source is assumed to produce the same magnitude in all filters.
The source is assumed to decay as t**(-1.0), and the rate is normalized so that the white filter produces 1 cps at 1000 sec.
The Rebinned Data for All_files combine rates from different exposures weighted by the expected rate divided by the observed sigma squared.
A plot of these data is stored in uvot_fluxes_wtd_date.ps and .gif.
A zero point of 20.29 is adopted for weighting rates.
*** Since no accurate position is available, set rates to 0. and compute ULs based on expected background in source aperture.
Because there are many possible positions for a source, the confidence levels should be increased for upper limits.
Using the ratio of the BAT region and the aperture of 784.0,
3 sigma should become about 4.8 sigma and 2 sigma should become about 4.2 sigma.
Accordingly confidence limits in the tables have been adjusted from 0.9987 to 0.99999834.
No adjustment has been made for the confidence limits for the rebinned data or the plots.
