... 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. ...

The sunspot cycle . The number of sunspots visible on the solar disk at any given time varies continuously, as sunspots are carried on and off the visible disk by solar rotation. At first glance, observations carried out over time periods of weeks suggest that the appearance of sunspots are stochastic, but observations over time periods of decades reveal an intriguing cyclic pattern of gradual increase and decrease in the average number of sunspots visible on the solar disk. ...

. The shell uses a command called test to evaluate conditional expressions. Full details of this command can be found in the test manual page. For example: if test ! -f $FILE then if test "$WARN" = "yes" then echo "$FILE does not exist" fi fi . First, we test to see if the filename specified by the variable $FILE exists and is a regular file. If it does not then we test to see if the variable $WARN is assigned the value yes , and if it is a message that the filename does not exist is displayed.
