---|---|---|---|
Description: fresnel_scale is sqrt(lambda * D/2), where lambda is the central wavelength of the observation and D is the average distance between the observer and the occulting ring. This is an average value for the entire occultation and is a measure of the limit on the radial resolution of ring structure due to diffraction. Note that the actual overall resolution is affected as well by the projected diameter of the occulted star and the instrumental time constant, if any. | |||
