When planning an observation it is necessary to consider how many events will be detected. ACIS's ability to process data is a function of the number of events which are detected, and the capacity of the telemetry to send those events to the ground. ACIS has buffering capability within the instrument, but if these limits are exceeded for any significant amount of time processing of additional CCD frames is stopped and data in subsequent frames are lost until the accumulated data are readout.
Processing and telemetry saturation will occur at the following situations.
