At the moment these are: HDU: CENTROID KEYWORD: GUIDESTA https://github.com/spacetelescope/stdatamodels/issues/340 HDU: PRIMARY KEYWORD: CALIB https://github.com/spacetelescope/stdatamodels/issues/342 HDU: PRIMARY KEYWORD: MSACFG10 https://github.com/spacetelescope/stdatamodels/issues/349 HDU: PRIMARY KEYWORD: MSACFG36 https://github.com/spacetelescope/stdatamodels/issues/349 HDU: PRIMARY KEYWORD: NEXTEND https://github.com/spacetelescope/stdatamodels/issues/345 HDU: PRIMARY KEYWORD: PA https://github.com/spacetelescope/stdatamodels/issues/342 HDU: PRIMARY KEYWORD: PPSDBVER https://github.com/spacetelescope/stdatamodels/issues/350 HDU: PRIMARY KEYWORD: R_DRZPAR removed in https://github.com/spacetelescope/stdatamodels/pull/316 HDU: PRIMARY KEYWORD: TEXPTIME removed in https://github.com/spacetelescope/stdatamodels/pull/277 HDU: REFSTAR KEYWORD: NUMREFST https://github.com/spacetelescope/stdatamodels/issues/341 HDU: SCI KEYWORD: SLIT_DEC https://github.com/spacetelescope/stdatamodels/issues/343 HDU: SCI KEYWORD: SLIT_RA https://github.com/spacetelescope/stdatamodels/issues/343

all of the remaining (I think) are captured by https://github.com/spacetelescope/stdatamodels/issues/344 HDU: TARG_ACQ KEYWORD: BCKGMETH HDU: TARG_ACQ KEYWORD: BCKGVALU HDU: TARG_ACQ KEYWORD: BOXPKCOL HDU: TARG_ACQ KEYWORD: BOXPKROW HDU: TARG_ACQ KEYWORD: BOXPKVAL HDU: TARG_ACQ KEYWORD: BOXTOTVL HDU: TARG_ACQ KEYWORD: CENBOXCL HDU: TARG_ACQ KEYWORD: CENBOXRW HDU: TARG_ACQ KEYWORD: CENITERS HDU: TARG_ACQ KEYWORD: COLMOMT2 HDU: TARG_ACQ KEYWORD: COLMOMT3 HDU: TARG_ACQ KEYWORD: CONVSTAT HDU: TARG_ACQ KEYWORD: CONVTHRS HDU: TARG_ACQ KEYWORD: CORR_COL HDU: TARG_ACQ KEYWORD: CORR_ROW HDU: TARG_ACQ KEYWORD: CRMETHOD HDU: TARG_ACQ KEYWORD: DTCENCOL HDU: TARG_ACQ KEYWORD: DTCENROW HDU: TARG_ACQ KEYWORD: EXTCOLST HDU: TARG_ACQ KEYWORD: EXTROWST HDU: TARG_ACQ KEYWORD: FINCOLDF HDU: TARG_ACQ KEYWORD: FINROWDF HDU: TARG_ACQ KEYWORD: GUIDERID HDU: TARG_ACQ KEYWORD: IDEAL_X HDU: TARG_ACQ KEYWORD: IDEAL_Y HDU: TARG_ACQ KEYWORD: IMAGETYP HDU: TARG_ACQ KEYWORD: IMCENCOL HDU: TARG_ACQ KEYWORD: IMCENROW HDU: TARG_ACQ KEYWORD: REFSTCAT HDU: TARG_ACQ KEYWORD: REFSTDEC HDU: TARG_ACQ KEYWORD: REFSTMAG HDU: TARG_ACQ KEYWORD: REFSTNAM HDU: TARG_ACQ KEYWORD: REFSTRA HDU: TARG_ACQ KEYWORD: REF_STAR HDU: TARG_ACQ KEYWORD: ROWMOMT2 HDU: TARG_ACQ KEYWORD: ROWMOMT3 HDU: TARG_ACQ KEYWORD: SAM_V2 HDU: TARG_ACQ KEYWORD: SAM_V3 HDU: TARG_ACQ KEYWORD: SAM_X HDU: TARG_ACQ KEYWORD: SAM_Y HDU: TARG_ACQ KEYWORD: SCIXCNTR HDU: TARG_ACQ KEYWORD: SCIYCNTR HDU: TARG_ACQ KEYWORD: STAT_RSN HDU: TARG_ACQ KEYWORD: TARGETV2 HDU: TARG_ACQ KEYWORD: TARGETV3 HDU: TARG_ACQ KEYWORD: TASTATUS HDU: TARG_ACQ KEYWORD: TA_DTCTR HDU: TARG_ACQ KEYWORD: V2_OFFST HDU: TARG_ACQ KEYWORD: V2_PLAND HDU: TARG_ACQ KEYWORD: V2_REF HDU: TARG_ACQ KEYWORD: V3_OFFST HDU: TARG_ACQ KEYWORD: V3_PLAND HDU: TARG_ACQ KEYWORD: V3_REF (as reported by the tool added in https://github.com/spacetelescope/stdatamodels/pull/337 and against a modified keyword dictionary that fixes most of the oifits related differences).

This issue will be updated as the above are categorized.
