... We employ Bayesian inference for the joint estimation of sources and background on ROSAT All-Sky Survey (RASS) data. ... Background maps were estimated in a single step together with the detection of sources without pixel censoring. ... The source probability is evaluated for single pixels as well as for pixel domains to enhance source detection of weak and extended sources. ... The spline fits the background component whereas count enhancements classify pixel (domains) with source contributions. ...
