April 15 AM: Compare Dolly/Diamond Motion when HPs Disconnected
Configuration:
- ACS: CCD Heat Pipes Disconnected at IF Plate
- Mounting: ACS in Handling Dolly in Diamond Orientation
- Cooling: Chillers
- Optical Source: HRC: Coronagraph
- Starting Temp: Ambient, at start of day
Results:
- Note: data noisy due to operating CCDs at room temperature (TEC off)
- Small motion ~0.5 pixel seen during warm-up
- Motion perpendicular to that seen in dolly/diamond with HP connected
- Chillers turned on to 14C caused no correlated motion
- Note: large jump at 17.3 most likely due to optical source change
