Bayesian calibration and map-making for radio intensity mapping experiments
hydra_tod implements joint Bayesian inference of sky temperature maps,
instrument gains, and correlated noise parameters from radio telescope
time-ordered data (TOD). It uses Gibbs sampling with MPI parallelization
to efficiently handle multi-receiver, multi-scan datasets.
The package accompanies the paper:
