T(λb) and dFb was also determined by the calibration. Using Ib obtained from equation (5), the airglow intensity (λ0) [R] is obtained by equation (3) as I(λ0) = ( Na - a ta Ib dFa - DKa ) / ( a ta T(λ0) ) = ( Na - A ta Ib dFa / T(λ0) - DKa ) / ( A ta ) ...(6) A, T(λ0), dFa are given from the calibration file, ta is an integration time, Ib is given by equation (5), Dka is given from counts at the edge of the CCD.
