[daip] Asking for help with XGAUS on a transposed moment map {External}

[Pichler Enikő]

Dear AIPS Group,

I would like to ask for your help regarding the XGAUS task. I am trying to fit Gaussians to the spectra of a moment 2 map (it is a VLA HI observation from 2008) and save the fits to individual files.

I am still a beginner at using AIPS, especially the tasks for Gaussian fits. The plots on the TV have the right ascension as the first axis, and I wanted to change that by using TRANS and setting the velocity as the first axis. However, when I try plotting with the transposed file as the input, I get an error message that a minimum of 6 pixels are required to do a fit. I have inspected the transposed cube with tvmovie and there was nothing on the images, all of them were blank.

May I have overlooked something while doing the transposing?

Thank you so much for your time in advance.

Sincerely,
Eniko Pichler
