... Meta Index / Home Page This program is designed to allow a user to recompute the photometry of one or more sources in an OM product source-list file, in one of several different ways, using specified parameters. ... This can significantly increase the accuracy of the photometry in the case of sources with one or more close neighbours. ... For the case of FAST mode data, omlcbuild uses the PSF to compute the photometry and obtains the background from pixels surrounding the source from. ...

... It is generally accepted that the mechanism, widely known as the Antikythera mechanism, was made in Rhodes at the height of the Roman Republic, as the island was known as the source of interesting mechanical automata. You can tell just by looking at it that the device is part of a larger object, and it is also obvious that there are geared wheels and other rotational elements within it. The device undoubtedly is an early computer and could be seen as the first planetarium. ...
