Ensemble Photo-z

These stages compute ensemble redshift histograms n(z) for bins

class txpipe.rail.summarize.PZRailSummarize(args, comm=None, aliases=None)[source]

Runs a specified RAIL “CatSummarizer” on each tomographic bin and collate the results from all the bins into a single file

“CatSummarizer” expects a catalog input, rather than a PZ input

Inputs:

  • binned_catalog: BinnedCatalog

  • model: PickleFile

Outputs:

  • photoz_stack: QPNOfZFile

  • photoz_realizations: QPMultiFile

Parallel: Yes - MPI

Configuration
  • catalog_group: (str) Required.
  • mag_prefix: (str) Default=photometry/mag_.
  • tomography_name: (str) Required.
  • bands: (str) Default=ugrizy.
