normal_optical_depth in Column_​Headers

Name: normal_optical_depthVersion Id: 1.0.0.0
Description: Normal optical depth is defined as the observed_optical_depth times the sine of observed_ring_elevation. Optical depth is equal to -ln(T), where the transparency T is the ratio of incident to transmitted radiant power, corrected for background_signal. Typically negative values are used to indicate the signal was too poor to allow the calculation of the value.
