How can I use the array footprint script to help reduce my SPIRE spectra?

There is a useful script in HIPE that helps the observer to carry out the reduction of spectra of extended sources observed with the SPIRE Fourier Transform Spectrometer. The following Herschel Science Centre short videotutorial explains how to use this script to reduce SPIRE FTS data: https://www.youtube.com/watch?v=xo0fc1XggIU The short videotutorial shows you how to visualise the source surroundings to see how much extended emission there is in the field of view, where to find the useful script and how to personalize it for a particular observation, how to overlay the FTS footprint plot on an image of your source, how to assess the background or foreground emission that may contaminate your spectra and how to assess whether or not there are off-axis detectors that you can use to eliminate this contamination. And, finally, for users who prefer to carry out this process outside HIPE, it explains how to do this in an external script. | |
