... Gauging the impact of executing science program across different COS/FUV lifetime positions . ... Changing Programs & Resolving Problems . ... The first such move occurred on 23 July 2012, when the COS FUV spectrum was moved to the COS FUV Lifetime Position 2 (LP2). ... It now appears that the move to COS/FUV Lifetime Position 3 will not occur until early 2015, and so a substantial fraction of Cycle 22 observationsare likely to occur at the COS FUV lifetime position 2, prior to the change. ...

... Constellations are star patterns on the sky ? ... Every star or galaxy we see can then be located on one of the 88 constellations into which we have divided the sky (coincidentally, the same number as there are keys on the piano.) Each of the 88 regions takes its name from the best-known star group or picture in that region, so the constellation Orion is the sector of the sky that includes the easily recognized star-pattern of Orion the Hunter. ...

... The model which is used to describe the energy response of the pn-CCD is the so-called partial event model (see []). ... An efficiency function CCE is defined that reflects the portion of charge collected if a photon is absorbed in a certain depth. This function is folded with the probability of absorption in that depth which is given by the absorption law. ... The detector response matrix is then filled using the partial event model with the parameters derived from the ground calibrations. ...
