GLESP is a pixelization scheme for the cosmic microwave background (CMB)
radiation maps. This scheme is based on the Gauss-Legendre polynomials zeros
and allows one to create strict orthogonal expansion of the map. The detail
for the GLESP idea can be seen in
"Gauss-Legendre Sky Pixelization (GLESP)
scheme for CMB maps",
International Journal of Modern Physics D, Vol. 14, No. 2 (2005),
pp275-290
(
astro-ph/0305537).
The current GLESP version is 2.0 and includes polarization
procedures
based on the formalisme described
in the appendix of Doroshkevich et al.
(
arXiv:0904.2517).
