This topic came up in a discussion of the Lugano experiment. I do not recall where. Anyway --
In the Lugano experiment, I suggested that it would have been a good idea to confirm the IR camera temperature readings by comparing them to a thermocouple (TC) held to the surface of the cell. This was what Levi et al. did in the previous experiment. In the previous experiments, the IR camera agreed with the TC to within 2°C. See p. 18:

People have said that the surface temperature of the Lugano cell probably varied from one location to another, such as between the flanges at the ends of the cell, or between "hills" and "valleys" in the uneven surface.
I do not understand why this temperature variation would be a problem. Suppose you hold the thermocouple inside a valley. You then compare the IR camera reading for that spot, in that valley, to the TC. If they agree, Bob's your uncle. Perhaps it would be a good idea to install 2 or 3 TCs in different kinds of locations: hill, valley, flange.
Am I missing something here? Would this not work because there a problem with something like IR camera resolution, or something else?
