Meurs Dunsink Observatory, Castleknock, Dublin 15, Ireland Aaron Golden IT Centre, NUI Galway, University Road, Galway, Ireland Abstract. Abstract: The calculation of flux upper limits in the sourcefree ("background") regions of photon-limited images is complicated by instrumental and statistical modeling and requires non-trivial computational effort. ... 2004). ...

... It is reasonable to expect a priori that the evolution of events is strongly time dependent, so the star formation history in a galaxy is another important parameter. Therefore, by calculating the evolution of events after a -function like star formation burst,   one gets a Green function for any arbitrary star formation history. ... The source evolution in a galaxy with given star formation rate is thus calculated as . ...
