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