Algorithm

- Check input
- Filter event file and Out-of-Time event file for GTI
- Remove noisy MOS CCDs
- Adjust bad pixels
- Calculate sky coordinates
- Create scaled images
     - Filter for events outside the FoV
     - for each energy band [
          - for each used CCD: 
             get exposure and counts in corners of the event- oot- and fwc- file  
             (E_obs, E_fwc, C_obs, C_fwc, C_oot)
          - for each used CCD: calculate ratio of count rates  
             w_ccd =  (C_obs-f_oot*C_oot)/E_obs  /  (C_fwc/E_fwc) 
          - calculate weight by averaging the count-rate ratios  W=avg(w_ccd)
          - create image from the eventfile
          - create image from the OOT eventfile and scale it with f_oot
          - create image from the FWC eventfile and scale each CCD by W*E_obs/E_fwc 
       ]
- Create vignetted exposure maps
- Create mask
- Remove temporary files
