ASAP doesn't read/recognise the source coordinate information from RPF files written with the Hobart multibeam correlator (standard ATNF multibeam correlator setup). For example scans = scantable('c071070506.rpf') scans.summary() Shows mostly correct information, but the RA and Dec are given as 00:00:00 etc for all sources.

This is not just a superficial problem, but it means that the velocity scale is incorrectly set as well. The coordinate information is written in the RPFITS file as it is correct when the same data is loaded with spc.

Please contact me for a sample file.

If you try and read RPFITS files directly from a DVD, rather than copying them to the harddrive first, ASAP returns the error:

ASAP>data = scantable('/Volumes/METHMB_PIGGYBACK_20/2007-04-29_2143_G5523501.rpf') Auto averaging integrations Importing /Volumes/METHMB_PIGGYBACK_20/2007-04-29_2143_G5523501.rpf...

When the same files are copied to the harddrive (with everything else the same), the files can be read OK.

Hi Guys

Thanks for your advice about setting DISPLAY properly. This worked, and I might have thought of it if the error message had not seemed to imply that ASAP could not find the PLOTTER function.

I am trying to get a very simple look at my mopra data. The next thing I tried to do, following the tutorial, also fails. Sorry for all the questions.

ASAP>q = s.auto_quotient()
