Detailed Description of the Data Product

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 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 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 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]

  • a “NResamples” 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].

Noisy or denoised convergence maps

Primary HDU:

$PrintPrimaryHeader fit/euc-le3-wl.xml le3.wl.2dmass.output.patchconvergence

Extensions:

For the array in HDU (HDU= 1..N, one per redshift bin), the following keywords are specified for each HDU (EXTNAME = “KAPPA_ZBIN_i”):

Header:

$PrintArrayHDUContents fit/euc-le3-wl.xml le3.wl.2dmass.output.patchconvergence KAPPA_ZBIN_i

The image contains a 3 dimensional image containing 2D maps for E and B modes (noisy or denoised according to DENTYPE parameters) 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 with no galaxy measured where inpainting has been performed).

SNR maps

Primary HDU:

$PrintPrimaryHeader fit/euc-le3-wl.xml le3.wl.2dmass.output.patchsnr

Extensions:

For the array in HDU (HDU= 1..N, one per redshift bin), the following keywords are specified for each HDU (EXTNAME = “SNR_ZBIN_n”):

Header:

$PrintArrayHDUContents fit/euc-le3-wl.xml le3.wl.2dmass.output.patchsnr SNR_ZBIN_i

The image contains a 3 dimensional image containing the 2D SNR images for E and B convergence, and an image with the number of galaxies per pixel.
