... Ideally, this map contains the energy offset for each pixel (expressed in analog-to-digital units, adu). ... High-energy particles hitting the EPIC pn CCD during the offset map calculation may cause the affected pixels to get offset values which are incorrect by a few adu. ... Due to the specific method of deriving the offset map onboard, the affected areas occur often in blocks of four consecutive pixels along readout direction. ... The affected pixels usually get an offset which is too small. ...

Next: ZGSC (Compressed GSC) and XSKYMAP . ... This is a preliminary report on an investigation of the quality and properties of plates digitized during creation of the Guide Star Catalog (GSC). The results will be vital for reclassifying GSC objects. ... Many objects are measured on more than one plate, and thus have multiple catalog entries. ... Among the shortcomings of the GSC are: biased magnitudes and incorrect classifications for certain objects, presence of artifact objects. ...

... CPS32 charged particle spectrometer chips were total dose tested to 10 krad. The major degradation of these devices, a linear increase in dark current, does not interfere with particle spectrometry operation. ... These results also indicate that imaging APS chips will suffer significant degradation, particularly due to dark current fixed pattern noise, but should remain useful for bright scenes to doses above 10 krad, especially with moderate cooling. ...

Seven months ago, on Mar 19, 2008, at 09:12 Moscow time, a new star appeared on the sky. The Sun had already risen over the Russia, but people of the Western hemisphere might be able to see by their eyes a faint starlet near one of Bootes constellation stars. This starlet appeared and faded by an order of magnitude in a minute. Astronomers named it GRB080319B or, informally, the Naked-Eye Burst, as it was twice as bright as human eye can see a star. ...
