The Miriad task smauvspec
supports a feature
of plotting the UV spectra along with the spectral line transitions
selected from
the JPL catalog.
This feature is useful for general
Miriad users to identify spectral lines contained in the UV data
using
the JPL catalog.
This method works well for a compact source at
the phase center. For an extended source, the S/N of the lines may be degraded
due to large phase change across the source. For weaker line in an
extended source, we recommended users to carry out the line
identifications in the image domain after full calibrations.
Here are two exmaples to show users how
to use the JPL catalog in spectral line identifications in the UV domain.
