Retrieval of surface from data across the MUSTANG field (Part 2)

Note
These are experimental data currently being analysed, not final documentation of research. They are posted primarily for the benefit of the research collaboration.

Description

The results presented here are based on same data and technique as presented in part 1; the only difference is that the Zernike Polynomials are defined on a circle of diameter 90m instead of 100m. The reason for doing this is that MUSTANG only illuminates the central 90m of the dish so there is essentially no constraint in the outer 10m. However, many Zernike polynomial pairs differ there the most and so previous results were highly correlated. This high correlation is much reduced here.

Fit up to third order

(Caption to be filled in)

Fits up to fifth order

As above, but fitting up to fifth order Zernike polynomial.
