DetailedDescStart 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. **Catalog columns** .. table:: :width: 100% +----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | **Catalog**: 70 columns table | +===========================+===========================================================================================================================================================================================================================================================+===========+============+ | **Name** | **Description** | **Unit** | **Format** | +---------------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-----------+------------+ | SOURCE_ID | Unique id | NA | FITS *K* | +---------------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-----------+------------+ | HALO_ID | Unique halo id coming from the Flagship dark matter halo catalog | NA | FITS *K* | +---------------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-----------+------------+ | KIND | Galaxy type: 0: CENTRAL, 1: SATELLITE, 2: QSO, 3: HIGH REDSHIFT, 4: STRONG-LENSING, 5: GLOBULAR-CLUSTER | NA | FITS *I* | +---------------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-----------+------------+ | RA | right ascension equatorial coordinates | deg | FITS *D* | +---------------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-----------+------------+ | DEC | declination in equatorial coordinates | deg | FITS *D* | +---------------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-----------+------------+ | RA_MAG | magnified right ascension | deg | FITS *D* | +---------------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-----------+------------+ | DEC_MAG | magnified declination | deg | FITS *D* | +---------------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-----------+------------+ | Z_OBS | redshift with peculiar velocity | NA | FITS *E* | +---------------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-----------+------------+ | REF_MAG_ABS | absolute magnitude used to scale emission lines width (usually in the r-band filter redshifted at z=0.1) | NA | FITS *E* | +---------------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-----------+------------+ | REF_MAG | magnitude used to rescale template (usually apparent SDSS r band z=0.1 AB magnitude, but absolute for QSO and High-z.
