        2) LyA detector ramped down and turned off
   
        Sequence: Manual

        SCI_SPEC: Following completion of the LyA observations of the synoptic
                  observation, the LyA MCP is ramped down and turned off.

        3) OVI detector turn on, OVI Stimulus Pulse Test conducted, HV ramped up 
   
        Sequence: Manual, TakeOVI_TxN 120 2

        SCI_SPEC: After switching off LyA detector, the OVI detector is turned on
                  a stimulus pulse test is completed

                  After powering on OVI detector, discriminator settings were discovered
                  to be incorrect. Discriminator settings were commanded to their nominal
                  values.
