Custom Query (241 matches)

I am trying to look for very weak emission from glycine in a MOPS spectrum. Unfortunately, the individual lines are not strong enough to be seen. What I would like to try is to overlay multiple versions of the spectrum that have been shifted in frequency so that the individual lines match up. I can then add all the spectra and see if there is anything there.

I have followed the instructions on the ASAP wiki for installation of 2.2.0 under Mac OSX (intel), but have had problems.

One minor issue is that steps b and c are identical. I think that one of them should be installation of numpy? I have obtained the latest number numpy-1.0.1-py2.4-macosx10.4-2006-12-12.dmg from ​http://pythonmac.org/packages/py24-fat/ and installed that but it made no difference.

All the steps work OK up to the point of running ASAP. ipython etc is fine and ipython -pylab returned no errors (it was definitely version 0.80). But when I try to run asap I get the error :

ASAP>

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.
