调研方向

Start with the linked wiki results and the handoff README at /n17data/cdaley/unions/analyses/shear_2d/bmodes_2d/mccd_v1363_inputs/handoff/v1.3.6.3_blind_A/README.md; the issue provides data locations and caveats but does not specify a repository change. Determine what shared inputs and outputs need to be documented in the project, then confirm the relevant deliverable with the project maintainers before considering the work done.

描述

Inputs and outputs from the Paper II B-mode pipeline runs on MCCD v1.3.6.3 vs PSFEx v1.4.6.3, so they can be reused (e.g. for E-mode work). Results: wiki. All paths are on candide and world-readable.

v1.3.6.3 handoff (blind A, for E-mode use): /n17data/cdaley/unions/analyses/shear_2d/bmodes_2d/mccd_v1363_inputs/handoff/v1.3.6.3_blind_A/ — layout, grids and caveats are in its README.md.

  • CosmoCov ξ± covariances. Each text matrix is ξ+ then ξ−, with θ increasing. _ng = Gaussian + non-Gaussian.

    • cov_reporting_g.txt, cov_reporting_ng.txt: 20 log bins, 1′–250′ (40×40).
    • cov_integration_g.txt: 1000 log bins, 0.5′–300′.
  • NaMaster Cℓ covariances (cl_cov_reporting.fits, cl_cov_fine.fits): EE/EB/BE/BB blocks.

  • Footprint mask (nside 4096), mask Cℓ, and measured survey properties cov_th_SP_v1.3.6.3.yaml:

    A [deg²] n_e [arcmin⁻²] σ_e
    2504.98 4.625 0.3786
  • Planck18. n(z) = v1.4.6.3 blind A as a stand-in until a v1.3.6.3 calibration exists.

  • CosmoCov does not apply the footprint boundary correction to the shape-noise term (a few % at most inside 12′–83′).

lc outputs, blind B (B-modes, PTEs, covariances; branch mccd-v1363), under /n17data/cdaley/unions/analyses/shear_2d/bmodes_2d/pure_eb/results/:

  • mccd_v1363/: v1.3.6.3.
  • psfex_mccd_footprint/: v1.4.6.3 cut to the 2491 deg² shared with v1.3.6.3. Its catalog and mask are in mccd_v1363_inputs/control/.
  • psfex_no_p7/: v1.4.6.3 without P7. Its catalog and mask are in mccd_v1363_inputs/no_p7/.

Diagnostics:

  • mccd_v1363_inputs/footprint_diag/ANSWER.md: why v1.3.6.3 covers ~400 deg² less (pointing coverage).
  • mccd_v1363_inputs/no_p7/QUICKLOOK.md: P7 attribution.
