QUB2PNG, Playing with Cassini VIMS cubes Options

[ugordan]

I've made some progress with the IR channel on VIMS, have managed to do partial calibration of the cubes. It's still buggy, but at least it's something. Here's a couple of rough results, all using R=5um, G=2um, B=1.26um.


In case of Saturn the green and blue channels were scaled up to match the intense thermal radiation. The cubes were flatfielded, quantum efficiency corrected and divided by solar spectrum, though I don't know if all the steps were carried out correctly. Dark current subtraction remains to be done - it's possibly the reason why the lower left Titan insets have banding in the red channel. I'm actually pretty satisfied with the way these two turned out, they are reminiscent of official VIMS surface composites, including the "blue" material.

Hopefully I'll be able to put something out to convert cubes to PNGs before long. A better solution would be a GUI but that's the tedious part for me.

Rest assured, ugordan, it's not lack of interest, just lack of time. What you're doing with QUB2PNG is really awesome. Have you contacted any members of the VIMS team to tell them about it?

A similar situation in my case - lack of time so only very rudimentary testing so far but this will soon change.

I've been spending huge amounts of time making DEMs of Saturn's satellites but fortunately the "development phase" is finally over. Stay tuned for "Iapetus the Movie" .

Emily, I'm curious - why do you think the VIMS team would want to know about this?

Anyway, here's the version that does flatfielding correctly (as far as I can tell):

P.S. Bjorn, that movie better be released soon or we'll start to get impatient now that we're know what's been cooking
