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.
To update antenna positions:
# in bash
uvedit vis=$PROJECT.rest out=$PROJECT.base apfile=$ANTPOS
To apply linelength corrections:
# in bash
linecal vis=$PROJECT.base
uvcat vis=$PROJECT.base out=$PROJECT.lc
