Demonstration

Raw data from PdBI easily amount to hundred of MB. It has thus been decided to leave the choice between two demonstration:

• In the first one, we start from the calibrated visibilities in uvfits format. The imaging and deconvolution steps are made inside MIRIAD and the visualization inside GILDAS.
• In the second one, we start from the raw visibilities in native PdBI format. Visibilities are calibrated inside GILDAS, the imaging and deconvolution steps are made inside MIRIAD and the visualization inside GILDAS. All communication between GILDAS and MIRIAD is done through FITS.

In both cases, both packages are called from the same python process.

Shell environment

To be ready to run the demonstration, we installed (1) no less than five different softwares. If you leaved the xterm you were working in, you have lost all the needed shell environment. So we gathered here what is mandatory to allow the demonstrations to run smoothly.

  pctcp104> export PATH=$PATH:$HOME/gildas-miriad/local/bin                    
  pctcp104> source $HOME/gildas-miriad/gildas-exe/pc-redhat7.2-ifc/bash_profile
  pctcp104> source $HOME/gildas-miriad/miriad/MIRSRC.linux                     
  pctcp104> export PYTHONPATH=$PYTHONPATH:$MIR/src/scripts/python

Those probably need a bit of adaptation to your own installation. For instance, pc-redhat-7.2-ifc may not be the system you are working on. To know what is correct for you, just look in the $HOME/gildas-miriad/gildas-exe directory.

Partial demonstration

The data and script needed to run the partial demonstration are available as a gzip tarball here (7.4 MB).

  pctcp104> cd $HOME/gildas-miriad
  pctcp104> tar -xzvf partdemo.tar.gz
  pctcp104> cd partdemo
  pctcp104> ./partdemo.py

If you want to come back to the orginal state, just type make clean at the prompt.

Full demonstration

Right now only the calibration inside GILDAS is implemented.

The data and script needed to run the partial demonstration are available as a gzip tarball here (790 MB).

  pctcp104> cd $HOME/gildas-miriad
  pctcp104> tar -xzvf fulldemo.tar.gz
  pctcp104> cd fulldemo
  pctcp104> ./fulldemo.py

If you want to come back to the orginal state, just type make clean at the prompt.
