 The purpose of the above was to measure the distorion of a lens so that it can be removed from an interferogram. You can enable distortion removal when the interferogram is first loaded.  To do that go to the configuration/preferences menu and select interferogram.  Click on the

+The user then needs to decide.  For cases where a known paraboloidial mirror is being measured the answer will be yes.
 If one is testing a sphere (Desired conic of 0.) or a mirror just staring to be corrected the user has a harder time deciding. One method is to heat a portion of the surface with a thumb before taking the interferogram.  That will raise the surface slightly.  If in the analysis that area is raise then the Z8 sign is correct.  If instead there is a dent then the z8 sign is inverted and the wavefront should been inverted.
