TN:110 Mean Square Difference of G-Tilt for Two Square Apertures
Abstract
Plans for quick-look data reduction involve forming an estimate of the value r0 based on the mean square difference of the G-tilts measured by two sub apertures of a standard type Hartmann sensor. Developing an r0 value from such a mean square difference requires knowledge of the coefficient relating the two, with accommodation for the fact that the sub apertures are square (as distinct from the previously analyzed version of this method, for which the individual apertures were circular). The value of this coefficient is developed in this work.
