Good going Derect, pretty interesting the Cak & Ha signal differences !
Are the darker areas in both, both relevant to cooler temps, maybe at different Alt/Height Levels, or are the Temps vastly different in Deg's in comparison, just wondering
Bob the darker areas are slightly cooler except the reverse would be true in the CaK as its inverted somewhat due to the way the Gstar captures the pics.I,ll have a better read to get a more exact answer.
