Lollipop is a Planck low-l polarization likelihood based on cross-power-spectra 
for which the bias is zero when the noise is uncorrelated between maps. It uses the 
approximation presented in Hamimeche & Lewis (2008), modified as described in 
Mangilli et al. (2015) to apply to cross-power spectra. This version is based on the 
Planck PR4 data. Cross-spectra are computed on the CMB maps from Commander component 
separation applied on each detset-split Planck frequency maps.
