Hello,
I am working with with a set of old JCMT 200-300 GHz data taken with the
DAS receiver. The line reductions and centering seem to work well in
Specx, but when I read the .fit files into Splat, the frequency axes for
the upper and lower sidebands seem to be off. (For example, a line at a
rest frequency of 260 GHz shows up in Splat with a LSB frequency of
-0.62 GHz and a USB frequency of 528.5 GHz.) I've tried changing default
options in Splat with the 'current spectrum units' tool, but can't seem
to find anything that works.... Do you have any ideas what might be
going on with this? Is there a way to make the axes read correctly with
this data? Thank you in advance for any help that you can give.
Sincerely,
Libby Miller
