Charge transfer efficiency

There are three basic types of loss which degrade CTE: fixed loss, proportional loss, and nonlinear loss. Examples are given of each type of loss and tech- niques for measurement of all three types of loss are . This approach depends upon efficient intergate transfer of individual electrons. Measurements are presented here of the charge transfer efficiency of . The charge transfer efficiency (CTE) of the UVIS detector has inevitably been declining over time as on-orbit radiation damage creates charge traps in the CCDs.

A set of formulae has been developed to correct aperture photometry for CTE loss with dependencies on the X‐ and Y‐positions, the .
