Detailed Description of the Data Product

This product contains the covariance matrix for tomographi galaxy-galaxy lensing E/B power spectra.

This output product is a fits binary table containing important input parameters as keywords in primary HDU, and a binary table in the next HDU with the covariance for galaxy-galaxy lensing E/B power spectra as described in

Extra metadata associated to the FITS container are the following:

  • SpatialCoverage a description of the spatial footprint [optional, cot:spatialFootprint],

  • CatalogSelection: describing the selection in the input catalogues [optional, up to 4 elements]

    • CatalogFileName: the name of the input catalogue [sys:dataFileName]

    • Selection: selection associated to catalogue [string]

    • CatalogUse: for which use case the catalog is employed (=[“PosShear”]) [string among “PosPos”, “PosShear”, “ShearShear”]

    • CatalogInfo: whether position or shear information is used in this catalogue [string among “Pos”, “Shear”]

    • CatalogOrder: order associated to catalogue for reporting (e.g. BIN_ID1)[int32]

Keywords

This fits table is expected to contain the following keywords in primary HDU, characterizing the important parameters of the product:

$PrintPrimaryHeader fit/euc-le3-wl.xml le3.wl.cm2pcf.output.pebposshear2d

Covariance table

The table (first HDU, EXTNAME=”RS_COVAR_EB_POSSHEAR2D”) will contain the following columns:

$PrintCatalog fit/euc-le3-wl.xml le3.wl.cm2pcf.output.pebposshear2d

Note

Under discussion is the possibility in the future of having as first HDU an estimate for Shot Noise :

  1. ELL1: first mean multipole [D, float64]

  2. ELL2: second mean multipole [D, float64]

  3. BIN_COMB1: first index for combination of redshift bins [J, int32]

  4. BIN_COMB2: second index for combination of redshift bins [J, int32]

  5. PE_PE_SH: covariance between E band power spectrum (shot/shape noise) [D, float64]

  6. PB_PB_SH: covariance between B band power spectrum (shot/shape noise) [D, float64]

  7. PE_PB_SH: covariance between E and B band power spectra (shot/shape noise) [D, float64]
