Abstract: The calculation of flux upper limits in the source-free ("background") regions of photon-limited images is complicated by instrumental and statistical modeling and requires non-trivial computational effort. ... The principal component in this is the time taken to pre-process and handle the 30 GB of RASS data rather than the calculation of each upper limit. ...
