I believe the correct helium coolant temperatures for Loop 1 are approximately 14.9K (supply) and 19.0K (return). These are based on the actual voltages being recorded by the LakeShore 218 temperature monitor (1.31V and 1.23V, respectively), and assume the diode thermometers follow the standard "DT-400" temperature curve. I incorrectly switched to the "DT-600" curve during the cool-down.
