Detailed description of the data product

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:

  1. RS_EST: choice of resampling estimator (Jackknife, Bootstrap) [StringKeyword]

  2. RS_STR: choice of resampling strategy (Catalog, Spatial) [StringKeyword]

  3. THMIN: minimal angular value chosen for spatial binning [DoubleKeyword]

  4. THMAX: maximal angular value chosen for spatial binning [DoubleKeyword]

  5. OATH: maximal open angle value used for the approximation [DoubleKeyword]

  6. THUNIT: unit of spatial distance [StringKeyword]

  7. BINSCALE: whether lin or log bins [StringKeyword]

  8. COORDSYS: if spherical or cartesian computation of distances [StringKeyword]

  9. SHE_SOFT: which SHE catalogue used [StringKeyword]

  10. SHE_SEL: selection for shear catalogue [StringKeyword]

  11. SOFTNAME: name of software used for 2PCF [StringKeyword]

  12. SOFTVERS: version of software used for 2PCF [StringKeyword]

Covariance table

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

  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: covariance between E band power spectrum [D, float64]

  6. PB_PB: covariance between B band power spectrum [D, float64]

  7. PEB_PEB: covariance between EB band power spectrum [D, float64]

  8. PE_PB: covariance between E and B band power spectra [D, float64]

  9. PE_PEB: covariance between E and EB band power spectra [D, float64]

  10. PB_PEB: covariance between B and EB band power spectra [D, float64]

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
