The thermal signature was very prominent in the Shortwave Infrared band (07) due to that spectral band’s greater sensitivity to higher temperatures — as well as in the Water Vapor infrared bands (08\/09\/10), since the rocket exhaust plume contained a large amount of superheated water vapor.<\/p>\n
