The following are new primary header keywords which will be added to the data
so that they can be updated by the code. They are also specified in the PCTETAB
reference file.
These are taken from the PCTETAB
CTE_NAME - name of cte algorithm
CTE_VER - version number of cte algorithm
CTEDATE0 - date of wfc3/uvis installation in HST, in MJD
CTEDATE1 - reference date of CTE model pinning, in MJD
PCTETLEN - max length of CTE trail
PCTERNOI - readnoise amplitude for clipping
PCTESMIT - number of iterations used in CTE forward modeling
PCTESHFT - number of iterations used in the parallel transfer
PCTENSMD - readnoise mitigation algorithm
PCTETRSH - over-subtraction threshold
PCTEFRAC - cte scaling frac calculated from expstart
PCTERNOI - the readnoise clipping level to use
#These are taken from getreffiles.c
DRKCFILE is a new dark reference file used only in the CTE branch *_DRC.fits
BIACFILE is a new super-bias reference file used only in the CTE branch *_BIC.fits
PCTETAB is a new reference file FITS table which will contain the software parameter switches for the CTE correction *_CTE.fit
This is the main workhorse function for removing the CTE from WFC3 UVIS images
Unfortunately this happens before anything else in wfc3, so there's a lot of reading files
at the beginning in order to populate needed information. The rest of the pipeline works
on one chip at a time and the structures are all defined to support that. None of these
structures are defined until the code enters the single chip loops. This differs from the
CTE correction in ACS which occurs later in the process after basic structures are defined.
