Detailed Description of the Data Product

This product contains 2D convergence maps (denoised and noisy), shear maps, noise standard deviation maps, and Monte-Carlo realisations for one or more patches.

This output product contains:

  • a cube map per patch associated to a FITS in [NoisyConvergence xml tag] containing:

    • a data cube (one redshift bin per HDU) containing the E/B convergence modes, the total galaxy weight per pixel, the galaxy density per pixel, the noise standard deviation map (STD), the shear, and the denoised convergence;

    • the Euclid visibility mask projected onto the patch.

  • a Monte-Carlo cube map per patch, per Monte-Carlo realisation, associated to a FITS in [SNRPatch xml tag] containing:

    • a data cube (one redshift bin per HDU) containing the Monte-Carlo realisation of E/B convergence modes.

  • a “NResamples” field to specify the number of samples that were used to compute the STD maps [int]

  • a “McSeed” field to specify the seed of the random number generator [int]

Convergence/shear cube

This FITS file is associated to a structure called NoisyConvergence (to be renamed after DR1). The patch number is given in the filename.
