Beyond Positional Priors ======================== XID+ has been designed such that additional prior information can be added (hence the +). This additional prior information could be on observables such as flux, or additional prior information on the model such as expected SEDs, redshifts etc. XID+CIGALE ---------- In collaboration with Will Pearson, (`Pearson et al 2017 `_) we have looked into introducing independent (i.e. no covariance between bands) flux priors for the SPIRE bands, by fitting ancillary optical and near-IR data with the SED fitting code, CIGALE. XID+SED --------------------- There is also an SED extension to XID+, which uses an emulated version of CIGALE to fit physical parameters such as starformation rate, redshift and AGN fraction directly on the map .. toctree:: :maxdepth: 4 ./notebooks/examples/XID+SED_example.ipynb XID+Extended Sources -------------------- An extension that can handle extended sources is actively being developed by `Raphael Shirley `_
