Quick-Start Advice for Running the Pixel-Based Correction for Serial CTE (aka X-CTE)
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. Code Updates:
