Frequency variation with temperature

Frequency deviation from the mean as a percentage, against temperature in deg C.



Regression slopes: F1/T = -1.44 %/degC;   F3/T = -0.19 %/degC;   F5/T = -0.40 %/degC;  

Q-factor variation with temperature

Q-factor deviation as a percentage of the mean, against temperature.



Regression slopes: Q1/T = 87.94 %/degC;   Q3/T = 58.21 %/degC;   Q5/T = 74.87 %/degC;  

Resistance variation with temperature

Looking just at f3/4 and f5/4 for the underlying temperature trend, free of moisture disturbances.
