Abstract
An experimental procedure is described for the absolute calibration of a low intensity radioactivated light source against a standard lamp. This light source then could be used periodically to check and calibrate the night airglow photometer which uses two filters to isolate a line emission from the continuum in the night airglow spectrum. The two filter problem is treated analytically and an expression is derived for calculating the spectral line intensity. Then it is shown that with certain assumptions a simple formula can be evolved and used with the experiment observations obtained with the two colour photometer to obtain the emission rate of photons for a certain wavelength (i.e. in a spectral line).
