July 14, 2012 vel = +12.74 Note that the actual value of the feature will be shifted to slightly longer wavelengths for the day side and slightly shorter wavlengths for the night side as there is a Doppler shift to the clouds, which are moving in the same direction as Venus for the day side and in the opposite direction for the nightside Looking at features: -------------------------------------------------------------------------------------------- ---------- N2+ band---------- Present in Combined Data?
