Retrieval of surface from data across the MUSTANG field

Note
These are experimental data currently being analysed, not final documentation of research. They are posted primarily for the benefit of the research collaboration.
Note
See also Part 2 of this is analysis.
Retrieved telescope phase maps from the individual pixels of MUSTANG. Only fitting for Zernike orders up to and including 3rd to concentrate on finding possible off-axis aberrations. Map are presented in same layout as on detector. Open map individually to see full detail.

Fits up to fifth order

The results below show that when fitting for all Zernikes up to and including fifth order, the output maps vary greatly between pixels.

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

Fits at Z=5 but starting from result of fit for pixel 5-3

The table below shows fits for up to fifth order Zernikes, but instead of usual fitting procedure, here the initial condition is always the fit result from the pixel in column 5, row 3. This is intended as a check of fit stability to changes in the initial point at which the minimiser starts.
