	C1P2 is shorthand for:

	SCLEAR; PSTACK(1,2); AVE; ALL; PAGE; SHOW

	The internal accum array is first cleared.  Then it ACCUMes the 
	first subscan number (.03 for filter bank data or .12 for hybrid 
	spectrometer data) of all the scan numbers in the ASTACK array.  
	The result of this ACCUM is then AVEd (averaged, divided by 
	the sum of the weights), BDROP and EDROP are set to 0 (ALL), and 
	the result displayed after clearing the graphics screen (PAGE; SHOW).

	Any non-integer fraction of the scan numbers is ignored
	by PSTACK.  There is no check on duplicate scan numbers.

	See the documentation for any of the individual steps for
	more information.
