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 shell-script (csh) form, assuming that the following have been defined at the top

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.

To update antenna positions:

# in csh
uvedit vis=$PROJECT.rest out=$PROJECT.base apfile=$ANTPOS

To apply linelength corrections:

# in csh
linecal vis=$PROJECT.base
uvcat vis=$PROJECT.base out=$PROJECT.lc
