Pseudo-Cl (or other C_l esimator) based likelihood approximation for cut sky with polarization AL Mar 2010 - fixed bug using on E, added support for multiple input simulated Chat for bias testing Apr 2011, added fullsky_exact_fksy Mar 2014 renamed from Planck_like, removed low-L likelihood to separate file Updated file structure, allows for binned HL likelihoods. Everything now in L(L+1)CL/2pi 2014 linear correction bin windows (e.g. for Planck lensing likelihood) Nov 2014: added generalization for more general map cross spectra
