Question regarding Huygens surface video Options

[Explorer1]

There was a publication a few months ago purporting to detect a fog bank, but Erich says while one can't exclude it, it's at the noise level.

A good summary of this claim here: http://www.planetary.org/blogs/guest-blogs...e-of-titan.html

Erich analyzed the little spots and determined they were all radiation hits on the detector, except for the one feature in the bottom left of image 897, which seems to be a dewdrop from methane sweated out of the ground by the lamp.

Thank you Ralph!

...But THE MOST IMPORTANT THING is to read the very detailed DISR Users Guide (which hasn't actually been on the PDS for terribly long)

Thanks, Ralph, that is an amazingly good reference.

Also, thanks to PDP8 for the fast cosine function. Will have to see how bogged-down I get in simulation

Erich analyzed the little spots and determined they were all radiation hits on the detector, except for the one feature in the bottom left of image 897, which seems to be a dewdrop from methane sweated out of the ground by the lamp. (Note they may be hits from neutrons from the RHUs - the rate of cosmic rays should be very low in Titan's thick atmosphere).

That's this paper.

The DISR lamp flux was constant after landing. The brightness distribution over the images slowly changed, however, most likely because of charge build-up on the CCD.

If there was a fog, Erich would have found it.
