            {list,fetch,process,analyse,collect,store,builddb}

Positional Arguments

task

Possible choices: list, fetch, process, analyse, collect, store, builddb

Task to run - one of: ‘list’ (list downloaded observations available for processing by captureBlockId), ‘fetch’ (retrieve data from archive, store under $BERK_MSCACHE location), ‘process’ (link measurement set under ‘staging’ directory, run calibration and imaging with Oxkat up to 2GC), ‘analyse’ (apply primary beam correction and make object catalogs with PyBDSF), ‘collect’ (collect data products for all processed observations - i.e., primary beam corrected images and catalogs), ‘store’ (store a more extensive set of processed data products for an observations for possible further processing in future), ‘builddb’(build survey-wide database and related products).

Named Arguments

-o, --observation

MeerKAT observation to fetch and process. For the ‘fetch’ task, this must be a link to an .rdb file on the archive, of the form https://archive-gw-1.kat.ac.za/captureBlockId/captureBlockId_sdp_l0.full.rdb?token=longTokenString. For the other tasks (‘process’, ‘analyse’), this should be the captureBlockId itself.
