PROGRAMS FOR MDI
			    ----------------


			      PROGRAM LIST

 - Monitor is a program for the operating system and housekeeping

 - Sequencer is main program and it has 3 submodes
	  alt is a 30 sec mode
          campaign is a 30 sec mode
	  prime60 is a 60 sec mode with 2 parts
	        structure is the low rate full disk images (2/min)
		dynamics is the low rate full disk images (1/min)
		    PLUS high rate other observations-alt or 
		    campaign (1/min)  



			   PROGRAM DESCRIPTIONS

 - Structure Program:

   The scientific objectives related to determining the solar internal 
   STRUCTURE require continuous  or nearly continuous observations for
   many months to years, so this data must be transmitted in the low bandwidth
   channel  

 - Dynamics Program:

   The detailed study of the solar convection zone DYNAMICS requires all 
   observable modes for a long interval.  During high-bandwidth telemetry
   intervals exceeding 72 hours, MDI transmits full disk Dopplergrams each 
   minute for the primary dynamics program.
