Before imaging, the data need to be corrected by applying the
calibrations determined above. The calibrater.setdata function selects which
data are to be corrected, and the calibrater.setapply function selects which
solutions are to be applied. The calibrater.setapply function may be run
several times (in any order) to specify simultaneous application of
different calibration components. The components will be applied by
the calibrater.correct function in the appropriate order according to the
Measurement Equation. In AIPS++, calibration tables are always
cumulative, and so are always applied to the observed data in the DATA
column. The corrected data are written to the CORRECTED_DATA column
in the MS, which will be used directly in imaging. Note: the observed
DATA is NOT changed. If you want to change the solutions you
have applied, you can create new calibration tables and correct the
data again - the CORRECTED_DATA column will be over-written.
