hi Mike,
	In _most_ circumstances I would agree. But for this case, we need an IR 
measurement I think. Most thermal cameras nowadays have a target crosshair and 
numerical measurement in the image. We don't need high accuracy, we just want to 
tell the APV chip temperatures to +/-5 deg C or so, I think, and see how the 
various chips compare (expect all quite the same, I believe +/-2 deg). It should 
be trivial, as long as someone can borrow a decent modern thermal camera.
