Ubuntu 18.04 anaconda python 3.7.3 issues ? #139

Closed stopsdj closed 3 years ago

stopsdj commented 3 years ago

I have created a virtual environment using anaconda python 3.7.3 on a system running Ubuntu 18.04. I have installed the stable aegeantools using "pip install AegeanTools" which seems to complete sucessfully. A colleague then attempts to use the installation with MEERKAT-GPS data and encounters problems (below). It has been suggested that the problem lies with aegean version issues and that reverting to aegeantools 2.0.2 might work

2) For AEGEAN, the problem seems to be to do with the WCS - the program starts but then quickly fails with a message:

"WCS does not have longitude type of 'RA', therefore (ra, dec) data can not be returned"

Have you any thoughts on this ?

Thanks and Best Wishes

Does MEERKAT-GPS refer to a galactic plane survey with Meerkat? It may be that the input data have coordinates that are lat/long instead of ra/dec, which is causing the error that you see.

Aegean shouldn't fall over when you use galactic coordinates, that's not the intended behavior.

After some testing I can confirm that the issue above is due to the input file having coordinates in galactic coordinates instead of equatorial coordinates.
