chavg
	Filter to average the data in a LTA file in time and/or frequency.  It
        reads an LTA file and outputs an LTA file with the specified
        channels averaged.  Averaging is done first along the time axis and then
        along the frequency axis.

 in (default=No default)

	Name of the input LTA file.


 out (default=No default)

	Name of the output LTA file.


 object (default=All sources)

	Regular expression for source selection.  Data for only the
        selected sources is averaged and written to the output 
        stream.


 integ (default=No integration in time)

	The time constant for integration in time as well.


 poln (default=-1 ==> ? - I forget which poln -1 implies!)

	Looks like this works on a single polarization at a time! :)) 


 chan (default=0,MaxChan,1)

	This takes 3 integers - start,stop,step.  Channels starting
        from the channel no. start will be averaged till the channel
        number stop in steps of step.


 norm (default=0 ==> Un-normalized)

	Set it to 1 if the data is to be normalized before the
        averaging operator is applied.
