The SciSim SPR search service helps you to find Software problem reports in the SciSim SPR database. You tell the search service what you are looking for by typing in a pattern for the SPR Id's and one or more regular expressions for the fields within an SPR. ... If a field in the search form is omitted, the search service will assume that you are looking for any match for that particular field. ... An SPR consists of fields that contain information. ...

... The improvement will be more pronounced in our crowded Wide Field Camera (WFC) images, and may be increased further through use of a more sophisticated method of combining the individual dithered images. Our analysis allows us to check for point spread function shape variations in the HST Planetary Camera (PC) field. ... In crowded field images, we are deriving information about the faint end of the luminosity function (LF) from the texture of the image background. ...

... 2 Magnetic Field . ... A magnetized bar has its power concentrated at two ends, its poles ; they are known as its north (N) and south (S) poles, because if the bar is hung by its middle from a string, its N end tends to point northwards and its S end southwards. ... That flow became known as an electric current . ... An electric current produced a magnetic force! ... The fundamental nature of magnetism was not associated with magnetic poles or iron magnets, but with electric currents . ...

. We give a review of some expander constructions using error-correcting codes and group algebras. We show that applying these constructions to properly choosed codes on modular curves one obtains some new intersting expander graphs. Go to the Laboratoire Poncelet home page.

... A second method to account for illumination problems in the flat fields is to remove the large scale pattern from the flat field itself. This is useful if there are no reasonable blank sky calibration frames and the astronomical exposures are evenly illuminated but the flat fields are not. ... Obviously, after having obtained the illumination corrected flat field it is reasonable to replace the original flat fields by the corrected flat fields in the reduction table. ...
