... Transforms a qpoe file according to the specified parameters. ... Any type of filtering can be applied to the input qpoe file, including region filtering. In addition, the size of the output event record can be different from the size of the input event record. Of course, usually one makes the output record equal to or smaller than the input. If the output record size is made greater than the input record, a warning is issued and the ``extra'' part of the record is undefined.) ...

As a result, a common magnitude scale (contour lines on the maps above, or color scale on Fig.1) will poorly display the short-duration events in a signal. Normalizing each line of the map (fixed duration) so it has unit variance (in effect dividing the energy map by the mean energy spectrum) at each duration restores more details of small-scale activity (Fig. ...

... Previous: A Posteriori Guidance for Astronomical Images . ... We present an original algorithm for the recognition of anomalous events in a CCD frame (i.e., cosmic hits, bad pixels etc.) The algorithm is able to distinguish between these events and real features by comparing the standard deviation and the kurtosis of a synthetic PSF, whose width is given by the user, and the corresponding values in a running window, whose size is chosen by the user, in the actual frame. ...
