This launches the processASKAP pipeline
--------------------------------------------------------------
There are two possibilities:
i) Determine the bandpass calibration tables - use '-b CAL_SBID' without '-i' or '-n' switches.
start_pipeline.py -b 20148
start_pipeline.py -b 20148 20435 20892
ii) Image one or more fields specified either as '-i SBID' or '-n ROW_NUM' where the survey
database row number is given. If the '-i' switch is used, also provide the bandpass SBID with '-b'.
start_pipeline.py -i 20908 -b 20892
start_pipeline.py -e 1 -n 412
Inputs for processASKAP.sh are provided by a sequence of sources:
i) All input variables have default values defined in
https://www.atnf.csiro.au/computing/software/askapsoft/sdp/docs/current/pipelines/ControlParameters.html
ii) These can be over-ridden with values passed to processAKSAP in a config file. This script compiles the config
file from three sources:
1. One of two parsets held in the aces repository: bandpass_default.parset and image_default.parset.
2. The chosen defaults parset (depending on the requested operation) can be over-ridden or augmented by values
in a local parset specified with the '-p' switch (default is pipeline.parset in working directory).
3. Final additions are made by the script itself; these reflect other command-line arguments.
