The Hi-Res readings were the colder readings. Because the instrument works in a non-linear way, they want to check for possible systematics being responsible for the change at Damascus rather than announce the the temperature fall is real. One of the possible models if the change is real is to consider that the heat engine is turned off for just Damascus. This might imply a moving "hot spot" beneath the surface, something similar to how the Hawiian Islands are made.

Also of interest is the identification of relic tiger stripes and offsets where one piece of stripe got separated by faulting from the main relic stripe body. It is sort of like a jig-saw puzzle or rubrics cube where the history needs to be re-assembled by partial rotations which in turn may give some idea of the timescale over which these rotations occured. Maybe one can trace the motions of the "hot spot" by the re-assembly of relic stripes.
