... 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. ...
