casa_cube is a python package that provides an interface to data cubes generates by CASA or Gildas. It allows the user to perform simple tasks such plotting given channel maps, moment maps, line profile in various units, correcting for cloud extinction, reconvolving with a beam taper, ... The syntax is similar to pymcfost to perform quick and easy comparison with models.

git clone https://github.com/cpinte/casa_cube.git cd casa_cube python3 setup.py install 

If you don't have the sudo rights, use python3 setup.py install --user.

To install in developer mode: (i.e. using symlinks to point directly at this directory, so that code changes here are immediately available without needing to repeat the above step):

 python3 setup.py develop 

import casa_cube as casa obs = casa.Cube('HD_163296_CO_220GHz.robust_0.5_wcont.image.fits') obs.plot(iv=0) 

For a line cube one must specify either the channel number (iv=) or a moment map:

obs.plot(moment=1,cmap='RdBu_r') 

import casa_cube as casa obs = casa.Cube('HD169142_2015-05-03_Q_phi.fits',pixelscale=0.01225) obs.plot()
