Abstract: The analysis of a planetary spectrum is most rapidly accomplished with the help of the curve of growth. When the atmosphere of a planet contains haze or clouds which cause the process of line formation to be dominated by ...

Abstract: Curves of growth suitable for the interpretation of hydrogen quadrupole lines in planetary atmospheres are calculated. Collisional narrowing of the line profile is included in the theory and it is shown how the curves of ...

Abstract: Specially prepared sections of pictures taken with the Mariner 10 television cameras are composited to show the time development of UV markings at various locations on Venus. A second series of composite pictures shows the ...

Abstract: We provide morphological and kinematic desc6ptions of the UV markings seen in the Mariner 10 imagery of Venus: the dark horizontal Y, bow-like waves, circumequatorial belts, subsolar disturbance, spiral streaks and bands, ...
