Paper Abstract

Interferograms of the front surface of a zenith-pointing 1.8 m mirror for a range of surface-to-air temperature differences were analyzed using two different methods to show that significant mirror seeing effects do not occur in the range of + or - 0.5 C, and may be acceptably small up to + or - 1 C. Mirror seeing was shown to comply with Kolmolgorov turbulence laws up to limits that are apparently due to the test setup enclosure. Small seeing effects were discernible despite much larger image error sources.
