Notes:
1. Blemishes are measured over an entire frame of data and counted within the frame
boundaries defined by A and B above.
2. Single pixel blemishes are defined as a pixel with an output as defined in C and D. A
bright single pixel defect occurs when the pixel exceeds the average output as defined
in C and a dark single pixel defect occurs when the pixel is below the average output
as defined in C.
3. Clusters are a group of adjacent blemishes.
4. Illumination analysis done at half saturation: the average pixel output of all pixels
within the frame is 128DN.
5. All tests conducted with gain off and skimming off with QTH lamp (color temp.
3200K) with Wide Band Hot Mirror (750nm cutoff).
6. Exposure time set to 10ms.
7. Camera operating in linear mode.
8. Camera operating under 25°C ambient temperature.
