Detailed Description of the Data Product¶

This product contains inputs to compute the 2D convergence “full-sky” maps based on multiple projection on patches.

To compute the E/B “full-sky” convergence maps using projection on a automatically defined multiple patches, the following set of parameters is needed:

how to handle reduced shear:
- NItReducedShear: the number of iterations used to compute the reduced shear [int]
- denoising parameters for reduced shear:
  - RSThreshold: Threshold to perform hard-thresholding in the reduced shear iteration
  - GaussSTD: the standard deviation for the Gaussian filter [double]
  - ThresholdFDR: the False Discovery Rate (FDR) threshold if applied [optional, double]
denoising parameters for final map: if Gaussian smoothing is performed, the value of the
- DenoisingAlgo: Name of denoising algo [string], currently only implemented: “GaussFilter”
- GaussSTD: the standard deviation for the Gaussian filter [double]
- ThresholdFDR: the False Discovery Rate (FDR) threshold if applied [optional, double]
NResamples: the number of resampling that needs to be performed for Noise/SNR maps [int]
how to handle the projection,
- Project: what type of projection [stc:projection]
- PatchWidth: size of the patches [double]
- PixelSize: size of the pixel in the patches [double]
- Nside: HEALPix nside of the final map [int]
- Overlap: fraction of the patches overlapping [double]
how to handle redshift:
- ZMin: min redshifts for the patches considered [double]
- ZMax: max redshifts for the patches considered [double]
- Nbins: the number of redshift bins [int]
- BalancedBins: if bins are balanced or not (in terms of number of galaxies) [bool]
how to handle gaps in data:
- NInpaint: number of inpainting iterations [int]
- EqualVarPerScale: , if a constraint is applied to have equal variance in/out of the masked area per wavelet scale [bool]
- ForceBMode: Flag to force B Modes to 0 in the gaps [bool]
- NInpScale: number of wavelet scales for inpainting [int]
- AddBorder: if an extra border is taken into account [bool]
