Measurements of CCD optical linearity for magnitude determination during meteor observations
Abstract
The results of investigating the dependency "light flux - magnitude" are presented. This dependency is used to determine the meteor brightness on CCD frames. This dependency is shown to be linear with the signal-to-noise ratio exceeding 10 dB. However, with low signal-to-noise ratio it is non-linear. This should be taken into account while measuring the faint meteors on single frames.
