FITS to AIPS

Here is an example of converting SMA data in Miriad format to uv-FITS format:

fits% inp
  Task:   fits
  in       = gc_rx1.lsb.tsys.cal.cont
  op       = uvout
  out      = /aips/FITS/SMACONT.UVFITS

The converted FITS data is exported to AIPS area and can be directly loaded with AIPS Task FITLD into AIPS. This conversion also supports multiple sources. For the spectral line data, the frequency or velocity might be screwed up in a case of multi-spectral windows. Users need to pay attention to the message reported from this program and may need to reset the frequencies in other software packages.

Here is an example to select a single spectral window to convert it to FITS:

fits% inp
  Task:   fits
  in       = gc_rx1.lsb.tsys.cal
  op       = uvout
  out      = /aips/FITS/SMALINE.UVFITS
  select   = window(15)                % spectral window 15

SMA users are encouraged to continue the image processing in Miriad . Miriad supports a variety of features particularly for spectral line observations and mosaic imaging of a large field.
