1.2 CCD Operations, Performance Parameters, and CCD . Transfer Curves . Low-light-level CCD performance parameters are grouped into four primary CCD operations: 1) Charge Generation (e.g. QE), 2) Charge Collection (e.g. MTF), 3) Charge Transfer (e.g. CTE), and 4) Charge Detection (e.g. Read Noise). ... Four Basic CCD Operations and Associated Performance Parameters and CCD Transfer Curves Used to Measure Performance . ... Charge Transfer Performance Parameters and CCD Transfer Curve Tests . ...

. Next: Generation from In-Orbit Data Up: EPN_ADUCONV Previous: Description Contents . Ground calibration data obtained from extensive measurements of X-ray emission lines and synchrotron lines (mainly flat fields). The gains of the individual readout nodes are derived by comparing the positions of the CTE corrected calibration lines (in ADU) with their energies. Michael Smith 2011-09-20

Photon Scattering: Basic Principle of Photon Scattering . Audio Narration is available . No Scattering: Photon Source and Detector . ... For optical photons, scattering goes as wavelength to the -4 power. In the case of blue photons compared to red photons, this means that blue photons are about 10 times more likely to get scattered than red photons. ... Watch the blue photons scatter away from the detector . ... Interstellar dust make stars appear redder than they really are . ...

Jeff mock supplied 6 different types of filters to use with the high resolution mode of the mock spectrometer. ... Plots were made of the time domain voltage response as well as the frequency domain power response. A decimation of 10 was used for the filter decimation. this gave a filter length of 80 coeff. The plots compare the filter shapes for these filter types (.ps) ( .pdf ) . ... Each color is a different filter type . middle: spectral density reponse for each filter . ...
