    DESCRIPTION       "There may be times when you will want to override 
		       certain SU level constraint checks or features that 
		       occur in the scheduling software.  

		       This can be done by the appropriate setting of fields
		       in this relation through the SCR form."

    FIELD  sunit_id

			 as specified in this table."

    FIELD  saa
        TYPE YES_NO_FLAG_TYPE
        DESCRIPTION     "When this field is 'N' then the SAA avoidance
                         constraint and restriction checks normally made in
			 the scheduing software may not be made.  The SAA
			 is a data quality issue with the HST and there are 
			 times when you will want to override the normal SAA 
			 restrictions (engineering proposals and some science
			 proposals do this).

			 This flag works in tandem with similar flags at the 
			 obset level, which controls PCS SAA checks, and at the 
			 alignment level, which controls SI related SAA checks.

			 By setting these SAA flags correctly you can schedule
			 SI states in the SAA that would otherwise not be 
			 permitted.  Likewise, you can turn of FGS SAA 
			 avoidance through these flags.

			 By default this field is 'Y' and the scheduling 
			 software will make this check. "

			 made.  This will allow SUs to schedule at orientations
			 that would otherwise fail. 

			 By default this field is 'Y' and the scheduling 
			 software will ensure that HST orientation at end of

			 contraints up to the beginning of slew to the next
			 scheduling unit. "

			 is the process of shifting an SU's activities down in
