Detailed Description of the Data Product

This product contains the covariance matrix for tomographic galaxy - galaxy lensing 2PCF.

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 tomographic galaxy-galaxy lensing 2PCF,as described in le3.wl.cm2pcf.output.posshear2d.

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 (Primary HDU)

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.posshear2d

Covariance table

The second table (second extension, EXTNAME=”RS_COVAR_POSSHEAR2D”) will contain the following columns:

$PrintCatalog fit/euc-le3-wl.xml le3.wl.cm2pcf.output.posshear2d

Note

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

  1. THETA_1: first angular separation (center of spatial bin) [D, float64]

  2. THETA_2: second angular separation (center of spatial bin) [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. COV_GTGT_SH: covariance between shear-position tangential components [D, float64]

  6. COV_GXGX_SH: covariance between shear-position cross components [D, float64]

  7. COV_GTGX_SH: covariance between shear-position tangential and cross components [D, float64]
