... List of output FITS files containing the spectrum of the background fluctuations extracted in equal-area annular regions at different offaxis values (between 0. and 12 arcmin). ...
... For a single circular, annular or rectangular (BOX) region the EXTENDED mode PSF is used which is based upon a King profile and is the most accurate parameterisation. ...
... pile-up (and extraction regions with larger annular inner radii) show increasing MOS ... sources which are analysed using annular extraction radii show increased MOSto-PN ...
