Detailed Description of the Data Product

This product contains full-sky convergence maps (denoised and noisy), shear maps, the noise standard deviation maps, and Monte-Carlo realisations (computed on the sphere).

This output product contains:

  • a cube map associated to a FITS in [Shear xml tag] containing:

    • a table (one redshift bin per HDU) containing HEALPix maps for 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 for the output resolution.

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

    • a table (one redshift bin per HDU) containing HEALPix maps for 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 table

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