rot_det_sky uses information from the previously created count image in sky coordinates to rotate the detector coordinate model particle background images produced by mos_back and model soft proton images produced by proton into images in sky coordinates. rot_det_sky is called by the perl script rot-im-det-sky which obtains the DETX,DETY and X,Y reference coordinates.
Warning and requirements: rot_det_sky is part of the esas package integrated into SAS, but it is limited to work within the esas data reduction scheme. This is specially true wrt the structure and names of the input files. In particular, rot_det_sky assumes that other tasks from the package, mos-spectra/pn-spectra and mos_back/pn_back have been successfully run for the recasting of the particle background, as well as proton for the recasting of the soft proton background.
