. 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

The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...

... We publish 16 Doppler imaging temperature maps for the years 1994-2002 of the active RS CVn star II Peg. ... Through Doppler imaging we want to study the spot evolution of the star and in particular compare this with previous results showing a cyclic spot behaviour and persistent active longitudes. ... The derived temperature maps are quite similar to the ones obtained earlier with a different methods, the main differences occurring in the spot latitudes and relative strength of the spot structures....
