... OM images are affected by a fixed modulo-8 pattern originating from the on-board centroiding of photon events to one eighth of the physical CCD pixel (see [ 1 ] or [ 3 ]) . The task ommodmap implements modulo-8 pattern correction by redistributing the photon counts over the -pixel areas of the image. ... With this, the total number of the photon events is conserved, as in the first method. ... Figure 2: OM grism image with a bright spectrum affected by the modulo-8 noise and coincidence losses. ...

... A theory suggests that a certain sub-class of gamma-ray bursts all have the same absolute magnitude. ... The author claims that this absolute magnitude is so different from that in the previous sample that this must belong to a new sub-class of gamma-ray bursts. ... To do this, there needs to be some feature in their spectra which correlates with their absolute magnitude. ...
