        1) OVI Detector Dark Rate Diagnostic
   
        Sequence: OVI_dark_chk 26627 51551

        SCI_SPEC: Determine Dark count rate for OVI detector. Instrument 
                  rolled to coronal hole, 5.0 Ro with 0.8 mm exposed mirror. 
                  Script engages OVI filter and then disengages it at end.
