During the E15 encounter, Galileo accquired the first segments of two massive hemispheric transects. 15ESREGMAP01, on the antijovian side, covers a large area within the famous G1 false color image showing the intersection of Minos and Udaeus Lineae. Presented here is an approximate natural color version along with a comparison with NASA's beautiful and oft-reproduced false color release from 1998:

Rhadamanthys Linea, a feature that that seemed to be comprised of a string of isolated dark spots at low resolution, was targeted for a better view on E14, E15, and E19. It looks as if Rhadamanthys is the "one that got away" as far as the pointing of the camera went, with the single-frame E14 shot missing it entirely and the E19 mosaic catching it only in the corner of each image.

VLOPHOT is a Very LOw phase PHOTometry frame (obtained in several colors), which was pointed not at any specific feature, but to the "shadow point" of the spacecraft (0 degree phase angle) to understand the scattering properties of the icy surface. |

My apologies for the mistake...from the pointer plot graphs, it looked awfully close to the intersection. Thanks as always for the insights. The imaging team deserves the greatest respect for making the most of a trying set of circumstances, and in most cases, bringing back the impossible. -------------------- ...if you don't like my melody, i'll sing it in a major key, i'll sing it very happily. heavens! everybody's all aboard? let's take it back to that minor chord...
