Side 1  T= 0.506@ 45 degrees /P polarization
Side 2  R=128 ppm

1.95 ± 0.11 ppm/cm

Phase map data  (about phase map format and filenames)
CIT Data covers the center 150mm
BS01-180, Dataset has only Tilt subtracted.  There are no missing data points within the set.
Z36_BS01-180  Zernike Coefficients for this data set (about Zernike Coeffs, we use the Wyko definitions)
Radius of curvature:  See last column at Index
Because of the 45° angle

Physical configuration:  See drawings at Index
Nominal:  25cm x 4 cm
Wedge:  1º  Installed with the thick side up - this orientation corresponds to the - 180º phase map designated -180
