[ascl:1101.009] MasQU: Finite Differences on Masked Irregular Stokes Q,U Grids

MasQU extracts polarization information in the CMB by reducing contamination from so-called "ambiguous modes" on a masked sky, which contain leakage from the larger E-mode signal and utilizing derivative operators on the real-space Stokes Q and U parameters. In particular, the package can perform finite differences on masked, irregular grids and is applied to a semi-regular spherical pixellization, the HEALPix grid. The formalism reduces to the known finite-difference solutions in the case of a regular grid. On a masked sphere, the software represents a considerable reduction in B-mode noise from limited sky coverage.
