User Parameters - Continuum Self-calibration

An option for continuum imaging is to run self-calibration at the same time. The algorithm here is as follows:

1. Image the data with cimager
2. Run source-finding with Selavy with a relatively large threshold
3. Create a component parset from the resulting component catalogue
4. Use this parset in ccalibrator to calibrate the antenna-based gains
5. Re-run imaging, applying the latest gains table
6. Repeat steps 2-5 for a given number of loops

Each loop gets its own directory, where the intermediate images, source-finding results, and gains calibration table are stored. At the end, the final gains calibration table is kept in the main output directory (as this can then be used by the spectral-line imaging pipeline).

Variable	Default	Parset equivalent	Description
DO_SELFCAL	false		Whether to self-calibrate the science data when imaging.
SELFCAL_INTERVAL	10	interval (ccalibrator)	Interval [sec] over which to solve for self-calibration.
SELFCAL_NUM_LOOPS	5	none	Number of loops of self-calibration.
SELFCAL_KEEP_IMAGES	true	none	Should we keep the images from the intermediate selfcal loops?
SELFCAL_SELAVY_THRESHOLD	15	snrCut (Selavy Basics)	SNR threshold for detection with Selavy in determining selfcal sources.
SELFCAL_SELAVY_NSUBX	6	nsubx (Selavy Basics)	Division of image in x-direction for source-finding in selfcal.
SELFCAL_SELAVY_NSUBY	3	nsuby (Selavy Basics)	Division of image in y-direction for source-finding in selfcal.
GAINS_CAL_TABLE	cont_gains_cal_beam%b.tab	none (directly)	The table name to hold the final gains solution. Once the self-cal loops have completed, the cal table in the final loop is copied to a table of this name in the base directory. This can then be used for the spectral-line imaging if need be. If this is blank, both DO_SELFCAL and DO_APPLY_CAL_SL will be set to false.
