Detailed Description of the Data Product

This product contains the covariance matrix for tomographic cosmic shear 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 cosmic shear E/B modes, as described in

  • 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 (=[“ShearShear”]) [string among “PosPos”, “PosShear”, “ShearShear”]

    • CatalogInfo: whether position or shear information is used in this catalogue (=[“Shear”]) [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.pebshearshear2d

Covariance table

The table (first HDU, EXTNAME=”RS_COVAR_EB_SHEARSHEAR2D”) will contain the following columns:

$PrintCatalog fit/euc-le3-wl.xml le3.wl.cm2pcf.output.pebshearshear2d

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 (shape/shot noise) [D, float64]

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

  7. PEB_PEB_SH: covariance between EB band power spectrum (shape/shot noise) [D, float64]

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

  9. PE_PEB_SH: covariance between E and EB band power spectra (shape/shot noise) [D, float64]

  10. PB_PEB_SH: covariance between B and EB band power spectra (shape/shot noise) [D, float64]

Warning

We have discussed to add later in the primary header

<IntegerKeyword name="SHE_SEL"/> <!-- ID of selection made (e.g. tomographic redshifts, stellar mass…) -->
