The spatial scale is 4"/pixel. Our point spread function is ~7" due to motion of the airborne telescope. The brightness contours range from 1 to 43 arbitrary units in steps of 2.
The 7.7 micron region is a sensitive thermometer of the jovian stratosphere sounding levels between 1 microbar and 10 millibars, far above the visible clouds. This region is totally blocked by methane in the Earth's atmosphere -it cannot be observed from ground-based telescopes. The KAO is the only observatory capable of investigating this spectral region.
The high spectral resolution of the KEGS instrument reveals individual emission lines of C-12 and C-13 CH4. At least 2 unknown emission lines were observed in the spectrum of the fireball. These may be due to high excitation states of CH4 or due to a different species altogether.
