Optimized WMAP7 likelihood code for multicore systems: OMPed loops and bottlenecks removed in the following codes:
Speed improvements apply to the Gibbs low-l TT likelihood, Master TT/TE/EE likelihood
Supplies an approximate replacement for the low-l polarization pixel likelihood based on a 2 band EE approach
See Dvorkin & Hu (2010) for speed and accuracy tests. After first evaluation typical improvement in speed is ~5xNcore
5 principal component (PC) functions of the GSR source function for determining the PC amplitudes of a model. [eta(Mpc), S1, ... S5]
