XID+ a new prior-based extraction tool for Herschel-SPIRE maps
  We present XID+ a new generation of software for prior-based photometry extraction in the Herschel SPIRE maps. Based on a Bayesian framework, XID+ allows the inclusion of prior information and gives access to the full posterior probability distribution of fluxes. XID+ is developed within the Herschel Extragalactic Legacy Project (HELP) and is available at https://github.com/H-E-L-P/XID_plus.
