CLEAN Map ps -- is a plot of the naturally weighted CLEAN image. The lowest contour levels (2 steps) on image is plotted at "clev" levels [Jy/beam], the peak brightness -- "max" values [Jy/beam]. The dashed contours indicate negative flux. The beam is shown in the bottom left corner of the images. The plot is in postscript format.

Received 2011 Sep 15; in original form 2011 Feb 6 ABSTRACT The bimodal galaxy distribution in the optical colour­magnitude diagram (CMD) comprises a narrow "red sequence" populated mostly by early-type galaxies and a broad "blue cloud" dominated by star-forming systems. ...

... These Facts and Questions pages mainly tell you how to use the Aberrator-interface and also explain the nature of the aberrations. ... Airy disc: the brightest spot of light when you look at a star in focus. This disc can contain a maximum of 84% of all the light that arrives from a star (perfect refractor telescope). MCT : Maksutov-Cassegrain telescope. A closed-tube mirror-telescope with a secondary obstruction. Less common than the SCT, this telescope uses a corrector (real glass). ...

... We guess it's almost impossible to create the site nowadays where all space relative philatelic materials (postage stamps, stationary, postal marks etc.) would be registered and presented. ... We tried to make such a step in April 2005, placing at the site first images of postage stamps with portraits of astronauts (cosmonauts, spacionauts, taikonauts:). ... All illustrative material (or simply speaking, all scans of stamps) are grouped in four sections: Countries , Years , Astronauts and Flights . ...
