Searching for codes credited to 'Hill, J. Colin'

Tip! Refine or expand your search. Authors are sometimes listed as 'Smith, J. K.' instead of 'Smith, John' so it is useful to search for last names only. Note this is currently a simple phrase search.

[ascl:2307.049] reMASTERed: Calculate contributions to pseudo-Cl for maps with correlated masks

reMASTERed reconstructs ensemble-averaged pseudo-$C_\ell$ to effectively exact precision, with significant improvements over traditional estimators for cases where the map and mask are correlated. The code can compute the results given an arbitrary map and mask; it can also compute the results in the ensemble average for certain types of threshold masks.

[ascl:2404.017] pyilc: Needlet ILC in Python

pyilc implements the needlet internal linear combination (NILC) algorithm for CMB component separation in pure Python; it also implements harmonic-space ILC. The code can also perform Cross-ILC, where the covariance matrices are computed only from independent splits of the maps. In addition, pyilc includes an inpainting code, diffusive_inpaint, that diffusively inpaints a masked region with the mean of the unmasked neighboring pixels.
