Thu CP1 Fill, new trip temperatures

Thu Oct 26 10:14:54 2023 INFO: Fill completed in 14min 49secs

Travis confirmed a good fill curbside.

Note that now the outside temperatures have dropped (and therefore also the thermocouple reference junctions) the TCs no longer drop down to -200C.

I increased the trip temperature from their summer setting of -130C to their winter setting of -100C this morning. The TCs min temps for today's fill were TCA=-125C, TCB=-119C.

The plot y-axis marker has been set to the new trip temp.
