... Using the uvby -photometry and proper motion data for about 5500 F stars within 80 pc from the Sun, we have studied velocity ellipsoid parameters and obtained the following results. 1) The sizw of all wllipsoid semiaxes increase systematically for groups of stars with the decrease of both temperature (at constant metallicity) and metallicity (at constant temperature). ... As a result, each of the three parameters - temperature, metallicity and velocity dispersion - is an age indicator. ...

. This image is a screen capture of the full width half max of the imager array taken on February 15, 2000. The left portion of the image is simply the fwhm calculations for each of the chips in the array. On the right side is the estimated fwhm corrected for wavelength. This takes all the different filters and converts the estimated seeing as if it were in i' I believe. It is useful as a measure of the consistency of image quality across the array. As you can see, it is quite good! . long@apo.nmsu.edu
