| Description: The value (Right, Left or Both) indicates the side of the spacecraft ground-track to which the antenna is pointed for data acquired within this file. The SAR (synthetic aperture radar) images stored in the BIDR (basic image data record) files are always acquired on only one side of the ground-track for each Titan pass. 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. |
