Introduction to Data

• Organized Chronologically

• All Data Collected at Ambient Temperature and Pressure

• Optical Source was either:

  • RAS/Cal Point Source (External to ACS)
  • Coronagraphic Spot (Internal to ACS)

• Motion is that of the Optical Source Position within the CCD Field of View

• Data is Presented as Delta X (Diamonds) and Y (Triangles) Pixels from Arbitrary Starting Point

  • HRC Pixels are 21 um
  • SBC Pixels are 25 um
  • WFC Pixels are 15 um
