How can I extract point source photometry from SPIRE maps?

Both point source photometry - from source fitting - and aperture photometry can be extracted from SPIRE maps. If you prefer to obtain aperture photometry from SPIRE maps, you should check the appropriate Herschel Science Centre short videotutorial for this method instead (https://www.youtube.com/watch?v=fjzf-VN_X0s). Point source photometry can be obtained from SPIRE maps either for a single source, or by using a source detection routine, such as Sussextractor to give you a list of detected sources in a field as input to extract photometry for multiple sources. There Herschel Science Centre has produced a short videotutorial on point source photometry, which reviews the methods of source extraction for single and multiple sources in a field, how to use the source extraction as input for photometry and which are the best photometric methods to use with your data. You can find this short videotutorial here: https://www.youtube.com/watch?v=nbN6OWtWIR0 | |
