(Inspired by this question)
One of the distinguishing features of Shuttle Columbia was its Shuttle Infrared Leeside Temperature Sensing (SILTS) pod. This was an experiment that took infrared imagery of the left wing and parts of the fuselage during entry. (It was deactivated long before the STS-107 accident so there was no data from it contributing to the accident investigation.)
Is there any imagery from this experiment available online? I found this paper (warning, pdf) that uses some results, but no actual imagery.
