XID+ a new prior-based extraction tool for Herschel-SPIRE maps
Yannick Roehlly, Peter D. Hurley

TL;DR
XID+ is a Bayesian software tool designed for prior-based photometry extraction in Herschel SPIRE maps, enabling the inclusion of prior information and providing full posterior flux distributions.
Contribution
It introduces a Bayesian framework for Herschel SPIRE photometry, allowing for prior information integration and comprehensive flux probability distributions.
Findings
Enables more accurate flux measurements in Herschel SPIRE maps.
Provides full posterior probability distributions for flux estimates.
Supports improved analysis of extragalactic sources.
Abstract
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.
