3D auroral volume emission rate estimate

Ok now it's like this: this stuff is my claim to fame. This is what I intend to base my PhD-thesis on. So the public/private redistribution of this images is restricted by these rules.

This is among the first really/relativelly sucsessfull 3D-reconstructions from the joint ALIS/Japan December 95 campaign. The group from Japan headed by Prof. T. Aso operated 2 imaging stations in Abisko and Nikkaloukta and the ALIS group operated 4 stations in Kiruna, Silkimoutka, Merasjärvi and Tjautjas. During this event there where desent conditions for observations from all stations except Merasjärvi, which had to much clouds. The stations was rotated to make observations in the core region.

These are the measured images that were exposed at 21:14:50 UT. One remark is in it's proper place: The japanese cameras were equiped with optics with approximatelly 90 degrees field of view and the swedish cameras were equiped with optics with approximatelly 72 degrees field of view. The images are monocromatic images of the auroral green line 5577 Å from O(1S)-O(1D).

A point that must not be forgotten is that the image quality if greatly reduced in several steps before this 8 bit gif image is rendered.

From these images a reconstruction was made with this result:

This is an image of a pseudocolour volume rendering of the auroral emission and a contour plot in the vertical east-west plane through the maximum intensity point, that was located slightly south of Kiruna ( = middle of the cube).
