BLOCK IDENTIFICATION: VIRGO Calibration (off-pointing) 3. PURPOSE: Determination of off-pointing sensitivity and monitoring of performance of detectors over time 4. SUB-BLOCKS: (see Note 1) NR.

(1) Matra procedure initiated by FOT (runs automatically without action from the FOT) for coordinated off-pointing calibration for VIRGO and MDI. It has to be run, however, during a contact period in order to get the high telemetry rate for MDI for imaging. (2) The first time this will be run as TSTOL procedures from FOT, the following degradation tests are included in our daily time-tagged commands. 6. SCHEDULING REQUIREMENTS: (see Note 3) Test 1/2: after day 30 on two consecutive days (e.g. day 31 and 32) Test 3, day 40 ("") Test 4, day 50 ("") Test 5, day 70 ("") Test 6, day 113 ("") Block 3.7, before start of HOI Block 3.8, after HOI Test 7, day 121 ("") 7. SPECIAL REQUIREMENTS: (see Note 4) 10h40 min contact time for Test 1/2 for MDI imaging (high rate telemetry) 8. SUCCESS CRITERIA AND/OR EXPECTED OUTPUT: Performance of LOI and MDI imagers and SPM detectors verified 9. RELEVANT PROCEDURES for Test 1/2: PROC22, 25; Test 3: PROC13, 14, 15; Block 3.7: PROC23; Block 3.8: PROC24 10. CROSS-REFERENCE TO TEST SHEETS: N/A (done with the FOT Procedures) 11.
