        The Chandrayaan-1 mission dictionary contains a class with attributes specific to the 
        Chandrayaan-1 mission and instruments. This dictionary was created for the migration
        of Chandrayaan data products from PDS3 to PDS4.
        
        v1.0.0.0 GEO/EAG 
        - Initial version of the Chandrayaan mission dictionary for PDS3 to PDS4 migration
        
        v1.1.0.0, T.Hare
        - Initial updates for M3

        v1.1.1.0, M. St. Clair
        - Further updates for M3
        - Pull release for 1.E.0.0
	    
	    v1.1.1.1, M. St. Clair
	    - add 'UNK' to spacecraft clock fields
	    
	    v1.2.0.0, J. Ward
	    - Added Mini-RF_Parameters class

            The value (Right or Left) indicates the side of the spacecraft groundtrack to which the 
            antenna is pointed for data acquired within a synthetic aperture radar (SAR) image. 
            Most SAR instruments acquire an image on only one side of the ground track at one time. 
            This value also indicates from which side the SAR image is illuminated. If the 
            spacecraft images to the left of its ground track (LOOK_DIRECTION = LEFT), the image 
            will be illuminated from the (viewer's) left side, and, conversely, if the spacecraft 
            looks to the right, the illumination will come from the right in the image file. 
            The direction of illumination is critical to interpretation of features in the 
            image. Mosaicked products may contain various combinations of source imagery. 
            For example, they may combine only left-looking observations (LOOK_DIRECTION = 'LEFT'), 
            only right-looking observations (LOOK_DIRECTION = 'RIGHT'), or a mixture of the two 
            (LOOK_DIRECTION = {'LEFT','RIGHT'}).
