______________________________________________________________________________________________
Note about upper limits:
threshold = 2 * delta_f
if ( f < threshold) then
if (f < 0) then
upper_limit = threshold
else
upper_limit = f + threshold
where f is the flux of the source, delta_f is the uncertainty of the source;
The upper limit is reported in the WPRO and standard aperture MAG columns;
the reported uncertainty is set to 9.99 mag.
