Getting flux from spectra
Posted: Sat Aug 30, 2014 2:20 am
Hello all,
I am also a neophyte in the radio astronomy world and I'm trying to figure out which task to use (mbspect, imspec, or imspect) to create some spectra. I'd like to create spectra centered around a star, at multiple frequencies and create output ascii files. I would also like to get spectra with the beam corrected flux on the y axis.
I've played with all three options and the best seems to be imspec, but the region seems to need to be in odd numbers of pixels. Using
plot=flux
options=list, noheader
I can get a spectrum with beam-correct flux in ascii form but not with the ideal region and not completely centered on the target. Is there a way to overcome this?
Thanks for the help,
Steve
