DESPHOT, described in the papers above, has been used to find the flux for objects in a prior catalogue. In the first (Roseboom et al. 2010) and second iteration of the algorithm (Roseboom et al. 2012)(XID), 24 micron and radio sources were used as prior positions. For the final iteration (DESPHOT) Wang et al. 2014 used the 250 micron sources detected with Starfinder as prior positions.

Installation

DESPHOT requires IDL, including the IDLlib and astron library. Make sure your file cotaining the DESPHOT code is also in your IDLPATH

Usage

DESPHOT requires the three SPIRE maps (ideally from SMAP) and a prior catalogue. Other parameters include the prf and segmentation threshold.

An example test script for running DESPHOT on one field can be found in testXIDcode.pro
