Detailed Description of the Data Product¶
A GalaxyCatalogProduct contains the following elements that describe a sky patch and associated information required to reconstruct galaxy spectra:
GalaxyCatalog: Galaxy catalogue filename, associated with the area it covers on the sky
SedLibrary: Library identifier, and data container to a the galaxy SEDs templates used to produce galaxy spectra
ExtinctionLawLibrary: Library identifier, and data container to the Extinction laws used to produce the galaxy spectra
ReferenceFilterFile: Data container with the filter throughput filename, used to renormalize the galaxy templates to apparent flux.
StampsLibrary: List of FITS files containing galaxy image thumbnails to paste in the simulated images (optional)
The name of the release is given by the DataSetRelease element in Header section of the data product.
GalaxyCatalog FITS format¶
The format of the input galaxy catalogue is specified by the FITS format sim.galaxyCatalog 0.5. More information can be found on the Redmine wiki. A catalogue contains the following columns.
Note that the fluxes include the lensing magnification factor. The intrinsic fluxes can be recovered by multiplying them by mu = (1-kappa)**2 - gamma1**2 - gamma2**2.
