DV07 Fast Switching Issues and Tracking

Test Matrix Progress Tracking

Note: All entries assume measurements at P=0, 90, and 225. Notes regarding servo tuning during these measurements:

(Az,El) = (120,60) Completed 2010-04-14: failures P0/P90/P225 = 19/0/0 (may consider repeating due to majority of measurements above E=60).
Repeated 2010-04-14: failures P0/P90/P225 = 4/0/0 (and E < 60 for all measurements). Will use this second measurement.

Limited Testing Matrix Inside Vertex SEF

The following table lists the matrix positions to be tested while DV07 is inside the Vertex SEF. These positions are chosen as the "tough spots" for FS performance (due to sidereal rate changes). All entries assume measurements at P=0, 90, and 225:
