... Programme . ... Abstract: The spectral energy distribution of the nucleus of Centaurus A, extending from radio to -rays, is similar to that of blazars, although the position of the low energy maximum is not well defined because of the uncertainty in the optical absorption. ... The observing technique consisted of scans with 24 arcmin amplitude, centered at the core and passing through the two inner lobes, which were used for instantaneous calibration. ...

... It is notoriously difficult to identify weak cosmic ray events in long exposure observations. ... The method is to compare the probability distribution function (PDF) of cosmic ray events between an observation and a dark frame matched in exposure time. We illustrate the basic idea using dark exposures from a Tek 1024 1024 CCD with varying exposure lengths and read-out times. ... Figure: Histogram of cosmic ray events in a two hour dark frame. ...
