- IFCENTER, FRQOFF1, and FRQOFF2 columns from
the FrontEnd table are reversed for each row where IFFLIPS is
true. This factorizes the sign issues when dealing with IF2 instead
ot IF1,
- The column BAND is read under the name PART for
IMB-FITS version lower than 2. Same for REC1 and REC2
read under the names RECEIVER and BAND respectively,
- REFCHAN is patched to correct values (instead of 1) when
dealing with continuum backend (1 channel per chunk),
- all the BackEnd columns, namely PART, REFCHAN, CHANS, DROPPED, USED, PIXEL, RECEIVER,
BAND, POLAR, REFFREQ, SPACING, and LINENAME are sliced into memory to more values than from the file
in order to factorize at once the MSET CALIBRATION BANDWIDTH
tuning. NAXIS2 is updated accordingly. See
section
for details,
- the columns MJD, INTEGTIM and ISWITCH are
compressed if MSET CALIBRATION BAD is NO (this is the
default). In this case all rows where ISWITCH is 0 are
removed. Two new columns FOREPOIN and BACKPOIN are added
as cross pointers between the original and compressed columns. See
section
for details.
- the DATE-OBS and DATE-END stamps of each subscan are
patched if MSET CALIBRATION MJDINTER is YES. See HELP
for details.
