I changed the distribution axis to ra so that I could try generating the transform independently of el, and apply it to a larger area of the ringmap without running into cumbersome memory (and I/O if writing out the operator) requirements. In this configuration, it ignores the dirty beam scaling to the signal prior, and takes an average of the weights across el to estimate the noise covariance. I'm not sure if the latter step is the best thing to do, as it may be sensitive to outlier elevations, especially if the full extent is included?

This makes it possible to construct an operator that is independent
of elevation.
