MADX -- A simple technique for source detection and measurement using multi-band imaging from the Herschel-ATLAS survey

25 Feb 2020 Maddox S. J. Dunne L.

We describe the method used to detect sources for the Herschel-ATLAS survey. The method is to filter the individual bands using a matched filter, based on the point-spread function (PSF) and confusion noise, and then form the inverse variance weighted sum of the individual bands, including weights determined by a chosen spectral energy distribution...
