Additional Comments 
-----------------------------------------------------------------------------------------------------------

CHANNEL 1 AND 2 GAINS
---------------------
Preliminary indications are that there are good mid-range values over bright targets.
No clipping or saturation.


TIME CODE OFFSET
-----------------------------
There is an offset of 15:49:12 between the MAS time and the RS-232
example ...

PORT 4  INFORMATION  
-----------------------------			
All bands dead through out the flight				 					   
Port 4 Dewar topped @ 0830L 
 

INSTRUMENT TEMPERATURE
----------------------
Minco looks likes it worked exceedingly well.  Very stable.  It looks like the MAS actually warmed
up a bit through the flight.  Broda indicated it was really warm up there, 50 deg??
