... Although the task is non-XMM specific, it is primarily intended to generate maps of the background in XMM EPIC images. The task does this by fitting a linear combination of background-model component images. The task takes three main inputs (see section 6 for details): (i) the Poissonian FITS image which is to be fitted; (ii) a list of model component FITS images; (iii) (optionally) a FITS mask image. The output is a single FITS image which represents the best-fit background model. ...
