Summary

The Chandra ABC Guide to Pileup discusses the phenomenon of pileup in Chandra X-ray observations, where two or more photon events overlap in a single detector frame and are read as a single event. Pileup occurs when source flux levels are high, causing a loss of information and affecting detected spectra and variability. The guide outlines methods for avoiding pileup, estimating its degree, and mitigating its effects in real data. Pileup can lead to a "hole" in the source image, grade migration, and distortion of the point spread function. The effects of pileup are energy-dependent, and its severity can be difficult to diagnose. The concept of a "pileup fraction" can be useful in preliminary assessments, but its definition and interpretation require careful consideration.
