Quantum Efficiency                                                            
                                                                              
Quantum efficiency is a measure of the fraction of the incident               
photons which strike a CCD and produce an electronic charge. A                
quantum efficiency of 1.0 means that all photons were recorded and            
a quantum efficiency of 0.0 means that none were recorded. Quantum            
efficiency can vary with wavelength due to the way different                  
wavelengths of light interact with the silicon in the CCD chip.               
                                                                              
The quantum efficiency of the flight CCDs were measured in the NRL            
CCD lab. The results, as functions of wavelength, may be viewed as
PDF plots or ASCII tables (recorded in the calib/quantum_eff/ 
directory).
