NVSS query and cross-matching script about aimfast HOT 4 OPEN

On a related note, what's the quickest to make an LSM from an image? My BDSM-fu is lapsed, so I was hoping someone could give me a quick recipe.

If you have stimela installed then you can spin a pybdsf cab as follows (this should return a model in fits and lsm):

import stimela


INPUT = 'input'
OUTPUT = 'output'
MSDIR = 'msdir'

IMAGE = ''
PIX_THRESH = 10
ISL_THRESH = 5


stimela.register_globals()

recipe = stimela.Recipe('Source Finder', ms_dir=MSDIR)
#JOB_TYPE='singularity', singularity_image_dir=os.environ["STIMELA_PULLFOLDER"])


recipe.add('cab/pybdsm', 'source_finder',
        {
            "filename"        :   "{}:output".format(IMAGE),
            "outfile"            :   "pybdsm_{}".format(IMAGE[:-5]),
            "thresh_pix"     :    PIX_THRESH,
            "thresh_isl"      :    ISL_THRESH,
            "clobber"          :    True,
            "catalog_type" :    "gaul",
        },
            input=INPUT,
            output=OUTPUT,
            label='src_finder:: Sourcery')

recipe.run()

PS: In the upcoming release aimfast will provide this functionality.

Or if you just want a pure* python solution, I still use this function which is based on one that Sphe wrote years ago:

If you give it a PyBDSF gaul file it should give you a Tigger LSM. Remember to adjust the cluster distance setting if you want the COPART business to make sense. It's being used in a weird way in this script:

https://github.com/IanHeywood/oxkat/blob/master/tools/identify_dE_directions.py#L181

• almost pure, it does assume tigger-convert is available from the command line.

Hmmm, at this stage even getting a .gaul is proving elusive... BDSM is hanging, seemingly forever, on fitting islands. Any idea how to tell it not to fit so hard?
