Note!	1) Cycle time indicates time between sampling windows. For the HF it
           indicates the average time between sampling windows.
	
	2) Lang = density mode, El = e-field mode


	3) From 16/8 -93 the New Bias scheme has been omitted due to memory problems.


	4) Cont means ContinuousLFMF mode where the LF and MF channels are sampled 
	   continuously for 50 sec. Data is stored in the burst memory until it is 
	   dumped.
