Sorry, I made a typo the graph title should say inductance in nanohenries (nH) not uH. The measured Ls for the 1206 capacitor is 1 nH.

Here's a simulation for the VSWR if the thermistors are not tracking perfectly. This is the case for when one thermistor is 90R and the other is 110R.
?
Whilst this still looks really good, the VSWR rapidly degrades to 1.04:1 at 50 MHz if the thermistor tracking degrades to 80R + 120R. I've not show this case as it is probably unlikely to happen unless the sensor has been stressed at some point.
