Hyper Phases

[James Nightingale]

We need to implement HyperPhases, which use a noise_scaling map from the results of a previous phase to scale the noise. The codes current state is as follows:

• The ci_fit module has a CIHyperFit class which computes the likelihood correctly.
• After a phase (parallel or serial), the noise scaling maps of the best-fit model for the full ci data are available as properties of the Phase's Result.
• There are integration tests which include a HyperPhase for all CTI directions.

Your job is to implement the HyperPhases such that they:

• Use the noise scaling maps of the previous phase.
• Extract these noise scaling maps as part of ci_data_fit to the same extracted dimensions as the ci_data and mask.
• Have available both hyper fits (Which use the noise scaling map) and oridinary fits (Which do not). This is so that we can visualize the result of scaling the noise.
