Next] [WFPC2 ISR Index] . ... The characteristics of charge transfer traps in the WFPC2 are examined and the effect they may have on observations are discussed. The dark tail created just above the location of the trap, as well as any bright tail created in the column above the trap when a bright source is clocked out during the readout, can be modeled as simple exponential decays. ... A portion of a WF2 image (before cosmic ray removal) showing the location of five of the seven traps on WF2. ...
