How can I carry out background subtraction on SPIRE spectra?
Posted by Mark Kidger, Last modified by Mark Kidger on 11 September 2018 02:28 PM

To find out about the steps to follow in reducing SPIRE spectroscopy and, in particular, how to carry background subtraction of spectra, there is a Herschel Science Centre short videotutorial that shows you the steps involved and also describes the data products that are available for which experts have carried out background reduction already. You can find the videotutorial here:

This videotutorial describes a useful interactive script for background reduction and shows a practical example of how to carry out background subtraction and the decisions involved in carrying out background subtraction interactively, identifying and eliminating interactively the outliers in background subtraction. It also gives you details of the available expert-reduced background subtracted spectra available as a Highly Processed Data Product.
