DataProductElementsEnd Detailed Description of the Data Product _________________________________________ .. DetailedDescStart This product contains 2D convergence maps (denoised and/or noisy), and/or SNR map for a patch. This output product contains three optional FITS structures: * a :ref:`noisy convergence map ` as a FITS data array (one redshift bin per HDU) containing the E/B modes for a patch and all redshift bins, the number of galaxies per pixel and with important input parameters 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 redshift bin per HDU) containing the denoised E/B modes for a patch and all redshift bins, the number of galaxies per pixel and with important input parameters as keywords. In particular, the **DENTYPE** keyword indicates that the data has been denoised [*DenoisedConvergence* xml tag] * a "NResamples" field to specify the number of samples that were used to compute the SNR maps [*int*] * a :ref:`SNR map ` as a FITS data array (one redshift bin per HDU) containing the E/B modes SNR maps for a patch and all redshift bins, the number of galaxies per pixel and with important input parameters as keywords [*SNRPatch* xml tag] * an associated spatial footprint (see `spatialFootprint here `_) [*cot:spatialFootprint*]. .. _twoDMassConvMapElementSF: Noisy or denoised
