CTE Tools

STEP 1)  CHOOSE THE ROUTINE YOU WISH TO USE FROM

            http://www.stsci.edu/~jayander/WFC3/WFC3UV_XCTE/CODE :


            raw2xcte_wfc3uv:    this performs the correction
                                on _raw.fits images, which can 
                                then be run through the calwf3 
                                pipeline.


            flt2xcte_wfc3uv:    this performs the correction
                                on _flt.fits or _flc.images images,
                                which can then be drizzled or
                                analyzed directly.
  

            In principle, it is slightly better to start with the _raw.fits image, since
            that way the x-CTE correction will be done before the y-CTE correction, as it
            should.  But in a practical sense, the difference is not very significant.



STEP 2)  Download the source code and compile with gfortran:


            gfortran raw2xcte_wfc3uv.F -o raw2xcte_wfc3uv.e



STEP 3)  Run the routine on an image:


            ./raw2xcte_wfc3uv.e iabcdefgq_raw.fits


            (the routine will create file  iabcdefgx_raw.fits,
             which can then be run through the pipeline)

Since this is an alpha version, we reserve the right to make significant changes.  Some improvements
are planned, but many will likely come as a result of user input regarding tweaks needed to make it
run on different platforms.  As such, we will be updating the code and providing notes below on
changes/improvements.
