Generating spectral index map

Postby amruth_alfred » Tue Oct 27, 2015 5:30 am


I am currently working on data reduction and have a problem in the imaging stage. I am using the 'clean' command to try to generate a spectral index map of my sources, using the 'nterms=2' command and weighting = 'natural'. The clean mode I'm using is mfs. The problem is that I am not getting a proper image when I view the filename.image.alpha ( which is supposed to be the spectral index map). It looks something like this, Image . This is after about 10,000 iterations, Image. I would be glad if someone could help me realise what I'm doing wrong.
