QML-FAST -- A Fast Code for low-$\ell$ Tomographic Maximum Likelihood Power Spectrum Estimation
QML-FAST provides a fast, optimal QML power spectrum code for low-ℓ tomographic analysis of up to dozens of correlated scalar fields on the sphere, with public release and validation showing gains over pseudo-C_ℓ at large scales.
