[Halld-cal] Pedestal Sigma vs. Temperature

[Zisis Papandreou]

Hi Tegan:

I agree with Elton's suggestion.  Please play around with the plots and we can discuss the variants this afternoon and try to pick something that displays the trend clearly.  This will also help our discussion on setting not only the temperature but also the overbias, in combination with the checks Ahmed is doing and work done in the past by Chile (S:N, resolution, etc).

Cheers, Zisis...
