                   COMMISSIONING PHASE BLOCK SHEET

1. INSTRUMENT: GOLF, Block 4

2. BLOCK IDENTIFICATION: Optimal channel switch-on

3. PURPOSE: Switch-on optimal channel for observations

4. SUB-BLOCKS: (see Note 1)
   NR.   IDENTIFICATION
   4.1   Switch-off
   4.2   Channel selection
   4.3   Switch-on
   4.4 & subsequent:  Parameter adjustments

   4.10  00:10       nom          NRT-d        m         Nom

   Continue for as long as necessary, but 1 week total is to 
   be expected

6. SCHEDULING REQUIREMENTS: (see Note 3)
   After GOLF offset pointing calibration for both Channel A and B
   (reference: joint sheet by Charra). Only to be executed if channel
   selected for science observations is different from the one
   currently switched-on. The decision on which channel to operate
   will be taken after completion and analysis of offset pointing
   calibration exercise.
   Subblocks 4.1, 4.2, and 4.3 to be executed on same day (during
   same contact). Subblocks 4.4 to 4.10 on subsequent days.
   
7. SPECIAL REQUIREMENTS: (see Note 4)
   Coordination with FOT. This operation may require reconfiguration of SVM.

8. SUCCESS CRITERIA AND/OR EXPECTED OUTPUT:
   Optimal channel ready for observations.

9. RELEVANT PROCEDURES
   1 - run "g_pwroff_r or m" STOL
   2 - run "x_exp_prep_on" sequence (TBC by FOT/MMS),
   3 - switch GOLF non-op heaters OFF (if not already done),
   4 - select relays position for Door and Mechanisms by use of 4 ON/OFF 
       commands (commands name depend on selected channel id.),
   5 - run "g_pwron_m or r",
   6 - run "g_observe_m or r".

10. CROSS-REFERENCE TO TEST SHEETS: (list identifiers for test sheets)
    Ask Jacques

11. RELEVANT SECTION OF TIMELINE (backpage)
    N/A


Note 1: Sub-blocks are functional units within a block. Operations can
        be interrupted between blocks, but usually not within a block.

Note 2: In this table the following information is sought:
        etc.??
