Detailed description of the data product¶
This output product contains in a FITS file data arrays with as HDUs the noisy/denoised E/B modes, SNR maps for a patch centered on a detected (and sufficiently massive) cluster with an associated spatial footprint (see spatialFootprint here). A ClusterID XML field as well as an optional ClusterMass field are also added to the product.
For the FITS product:

ArrayHDU (optional): Noisy convergence map¶
The following keywords are specified for each hdu:
EXTNAME = “NOISY_KAPPA_PATCH”
The image contains a 3 dimensional image containing the 2D noisy E/B modes.
ArrayHDU (optional): Denoised convergence map¶
The following keywords are specified for the second HDU:
EXTNAME = “DENOISED_KAPPA_PATCH”
The image contains a 3 dimensional image containing the 2D denoised E/B modes.
ArrayHDU (optional): Galaxy Count map¶
The following keywords are specified for each hdu:
EXTNAME = “GALAXY_COUNT”
The image contains an image with the number of galaxies per pixel in the maps (can serve to derive a noise level or to identify zones where inpainting has been performed- zone with no galaxy measured).
ArrayHDU (optional): SNR map¶
The following keywords are specified for each hdu:
EXTNAME = “SNR_PATCH”
The image contains a 3 dimensional image containing the 2D noisy E and B modes, the 2D denoised E and B modes if provided, and an image with the number of galaxies per pixel in the redshift bin (can serve to derive a noise level or to identify zones where inpainting has been performed - zones with no galaxy measured).
