Reconciled with block: tega_door_open\r36_TA1_6

Objectives: The Carrier valve since a sol 111 has been consistently opening on command. This block provides a confidence test for valve opening and closing on command. The final state of the carrier valve shall be in the “Open” state. It will also do a re-check of our ability to regulate gas via the bypass and oven inlet valves. (The test on Sol 118 gave a too high pressure)

Configuration: Needs to be run other than first thing in the morning because we don’t want this run at a lower PEB temp of -40. This procedure may begin with TEGA off, or it may be tacked on the end of some other procedure.
