DetailedDescStart This product contains 2D "wide-field" convergence maps (denoised and/or noisy), and/or SNR map and Monte-Carlo realizations based on multiple projected patch. This output product contains four optional FITS structures: * a :ref:`noisy convergence map ` as a FITS data array (one HDU per redshift bin) containing the E/B modes in HEALPix maps. Important input parameters are stored as keywords, in particular, the **DENTYPE** keyword indicates that the data has not been denoised [*NoisyConvergence* XML tag] * a :ref:`denoised convergence map ` as a FITs data array (one HDU per redshift bin) containing the denoised E/B modes in HEALPix maps. Important input parameters are stored as keywords, in particular, the **DENTYPE** keyword indicates that the data has been denoised [*DenoisedConvergence* XML tag] * several :ref:`Monte-Carlo maps ` as multiple FITS data arrays (one FITS per realization) containing the E/B modes in HEALPix maps for a realization (one HDU per redshift bin), of same format as the previous ones [*MonteCarloMap* XML tag] * a :ref:`galaxy-count HEALPix map ` as a FITS data array (one HDU per redshift bin) containing the number of galaxies per pixel [*GalCount* XML tag] * a :ref:`patch position array ` as a FITS data array containing the list of positions for the center of the patches used to compute the convergence maps [*ProjCenterPos* XML tag] * a :ref:`SNR map ` as a FITS data array (one HDU per redshift bin) containing the E/B modes SNR maps [*SNRMaps* XML tag] * a "NResamples" XML field to specify the number of samples that were used to compute the SNR maps [*int*] * a "McSeed" field to specify the seed of the random number generator [*int*] * an associated spatial footprint (see `spatialFootprint here `_) [*cot:spatialFootprint*]. **Primary HDU**: All products have same primary array, described as follows, characterizing the important parameters of the product, such as the coordinate system: $PrintPrimaryHeader fit/euc-le3-wl.xml le3.wl.2dmass.output.patchessphereconvergence They however differ in the information stored in the next HDUs. .. _twoDMassConvMapElementPS: Noisy or denoised convergence maps/Monte Carlo realizations +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ For the array in HDU (HDU= 1..N, one per redshift bin), the following keywords are specified for each hdu, starting with required HEALPix keywords (see https://healpix.sourceforge.io/data/examples/healpix_fits_specs.pdf): *Content*: $PrintHDUTableContents fit/euc-le3-wl.xml le3.wl.2dmass.output.patchessphereconvergence KAPPA_ZBIN_i For each redshift bin (1 hdu per redshift bin), the E/B modes are stored in a 2d binary table with two vector columns (**KAPPA_E**, **KAPPA_B**)s. .. _twoDMassPosArrayElementPS: Patch positions: array with center of projection +++++++++++++++++++++++++++++++++++++++++++++++++ For the first HDU, the named is set as: *Content*: $PrintHDUTableContents fit/euc-le3-wl.xml le3.wl.2dmass.output.patchesspherepos PATCHES_POSITIONS Two columns (**RA_CTR**, **DEC_CTR**) are reported in this extension, containing the position of the centre of the patches used to compute the projections. .. _twoDMassGalCountMapElementPS: Galaxy-count maps +++++++++++++++++ For the array in a HDU (HDU= 1..N, one per redshift bin), the following keywords are specified, starting with required HEALPix keywords (see https://healpix.sourceforge.io/data/examples/healpix_fits_specs.pdf): *Content*: $PrintHDUTableContents fit/euc-le3-wl.xml le3.wl.2dmass.output.patchesspheregalcount GALCOUNT_ZBIN_i According to HEALPix convention, for each redshift bin, a **GALCOUNT** column will contain the number of Galaxies measured per pixel on the sphere and redshift bin considered, which can also be used to identify the area inpainted (pixel without measured galaxies). .. _twoDMassSNRMapElementPS: SNR maps +++++++++ For the array in HDU (HDU= 1..N, one per redshift bin), the following keywords are specified for each hdu, starting with required HEALPix keywords (see https://healpix.sourceforge.io/data/examples/healpix_fits_specs.pdf): *Content*: $PrintHDUTableContents fit/euc-le3-wl.xml le3.wl.2dmass.output.patchesspheresnr SNR_ZBIN_i According to HEALPix convention, for each redshift bin (1 hdu per redshift bin), the maps are stored in a 2d binary table with two vector columns (**SNR_E**, **SNR_B**), associated to the E/B SNR maps. ..
