1149271 FUV HVNom
Modification Test
•
•
•
•
•
Lowered HVNom by 140/125 volts
Modal gain dropped to prelaunch values
Very small effective area decrease
No sign of the divot and clod
Expect to recommend permanent change to the
voltage

11492 visits 01 and 71 FUV Comparison
6
11478 NUV Flat Fields
• First 36 visits completed last week
– 36 more visits in proposal as contingency
• Analysis shows that on-orbit flat (300
counts/pixel) is consistent with the ground flat
(12,000 counts/pixel), so no further visits are
needed
• Upcoming High S/N observations will be used for
verification
