Phase map data  (about phase map format and filenames)
CIT Data covers the center 150mm
2ITM02-0, Dataset has Tilt and Power subtracted (Z1, Z2 & Z3), there are no missing data points within the set
Z36_2ITM02-0  Zernike Coefficients for this data set (about Zernike Coeffs, we use the Wyko definitions)
Radius of curvature:  See last column at Index

Off Axis Phase map data
CIT Data covers 150 mm centered at 33.5334 mm to the right of center along the x axis when viewed facing side one with the thin side up ( -0 data set)
2ITM02-OA  Dataset has Tilt and Power subtracted (Z1, Z2 & Z3), there are no missing data points within the set



Physical configuration:  See drawings at Index
Nominal:  25cm x 10 cm
Wedge:  0º34'  Installed with the thick side up - this orientation corresponds to the - 180º phase map designated -180
