Figure 8(a) is the fitting curve of real depth and apparent depth
, and (10) is the modified relation between real depth and apparent depth
The depth of these bands needs to be subtracted from the apparent depth
scale (on the right side of the plot) to arrive at a correct depth to the water table.
The apparent depth
of the source beds, as seen by the Mars Observer Laser Altimeter aboard MGS, is less than a few hundred meters below the surface -- well within the assumed permafrost region.
Sadly, despite his willingness to accept responsibility, he had no answers to the most pressing questions and no apparent depth
in any of his explanations.
The "apparent depth
" is the distance between the peak of the ridge and the bottom of the groove.
However, the major factors masking the repetition of the depicted depth were the perceptual effects that caused changes in the apparent depth
with different viewing conditions.
