cubevis 0.5.21

visualization toolkit and apps for casa

This is a beta-release quality package. This package relies on the CASA data processing system for radio telescopes as the processing backend while providing control and visualization using Bokeh.

Introduction

These tools are primarily based on Bokeh. The GUIs use Python and CASA to provide image access while a generated JavaScript interface provides a control front-end.

Interactive Clean

Interactive clean is the primary application provided by this package. It allows for visualizally observing and controlling the image reconstruction performed by CASA. The primary CASA tasks used to perform the image reconstruction are tclean and deconvolve.

Usage

This example provide a summary of how to use interactive clean from Python:

from cubevis import iclean

iclean( vis='refim_twopoints_twochan.ms', imagename='test',
        imsize=100, cell='8.0arcsec',
        phasecenter="J2000 19:59:28.500 +40.44.01.50",
        outlierfile='test_outlier.txt',
        niter=50, cycleniter=10, deconvolver='hogbom',
        specmode='mfs', spw='0:0' )

For this sample, the test measurement set is available, while the outlierfile would look something like:

imagename=try_multifield_1
imsize=[80,80]
cell=[8.0arcsec,8.0arcsec]
phasecenter=J2000 19:58:41.095 +40.56.01.043
