Importing Data from MIRIAD

A filler routine is currently being developed to convert native MIRIAD format data into a CASA measurement set, but it has not yet been completed. The following steps describe how to use FITS format files to transfer CARMA data into CASA, and should still be useful even after the filler is operational. At that time, a description of how to use the CARMA filler routine will be added to this page.

This page assumes you have MIRIAD already installed. All MIRIAD commands are given in their command-line form.

Preparing MIRIAD data for export to FITS

If you need to apply an update for the antenna positions, or linelength corrections, you should do these before exporting to FITS:

uvedit vis=$PROJECT.rest out=$PROJECT.base apfile=$ANTPOS

CASA does not handle linelength corrections, so if you want to apply these you should do it in MIRIAD before exporting to FITS:

linecal vis=$PROJECT.base
#gpplt vis=$PROJECT.base yaxis=phase nxy=5,3 device=/xs options=wrap
uvcat vis=$PROJECT.base out=$PROJECT.lc
