Fig. 4From: Calibration of imaging parameters for space-borne airglow photography using city light positionsSensitivity spectrum of the camera obtained from the laboratory experiment. The response of the sensor to monochromatic light was examined in 10-nm intervals. The mean raw count per pixel per cd/m2 is normalized by divided by the peak mean count of the green channel. The wavelengths of the major emission lines are also plotted Back to article page
