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.
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
