Imaging Pipelines

Getting a Measurement Set

First create a measurement set from the TART telescope. This is done using the tart2ms package:

sudo pip3 install tart2ms --upgrade

Then download a some JSON data from the TART and save it as a measurement set.

tart2ms --api https://tart.elec.ac.nz/signal --ms tart.ms

Using wsclean

This will make a basic image that doesn't really do clean at all. Its pretty awful really.

export OPENBLAS_NUM_THREADS=1; wsclean -v -scale 0.1 -size 1750 1750  \
	-make-psf -pol RR \
	-auto-threshold 3 -mgain 0.4 -gain 0.1 -niter 5000 tart.ms

Using disko

This uses an experimental package that makes round images.

sudo pip3 install disko --upgrade

disko --ms ${MS} --SVG  \
	--arcmin 60 --nside 24 --fov 170 --nvis 5000 \
	--dask --tikhonov
