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. -------------------- |

Ahh - congratulations - to be honest, command line based makes a lot of sense as then we can write nice long batchfiles to process a whole load of it
