for any elevation, capture an image with the 4D interferometer
save the data including: img, mask, elevation
compute a zernike fit (surf_fit[1,2,3,4,5,6], zcoeff=zz) & zern5=zz
iterate untile a full measurements cycle is completed
save zern5, elev in a file in meas/astig/tracknum/astig_lut.sav
copy the file in calib/...../data/astig_lut.sav
data are saved in the calibration file in the form:
elev (elevation, degrees, double)
zern5 (zernike term 5 =Z5, m RMS over the pupil,
as measured by the interferometer and RRoptics, wedge=0.5)
