Transfer Orbit Data Examples

• ACIS-I: Flight Contamination Monitor
  Description: X-rays from sources in the Sun Shade Door are detected by the ACIS after they reflect off of the HRMA surfaces.

• HRC-I: HV ramp-up tests
  Description: Early in transfer orbit phase HRC-I has high count rate, presumably due to residual outgassing. Timing plots show effect of HV being increased.

• HRC-S: pulse inject test
  Description: With HRC-S HV off, pulses are injected into the readout amplifiers and processed. Timing plots show selected pulse location changing with time. Electronics-only FWHM of 7.3 microns seen.
