The range of interest for these operating variables were:

- V_b: from 0.5V below to 0.5V above the operating range: 19V-21V

* V_b: from 0.5V below to 0.5V above the operating range: 19V-21V

- T: 0-above room temp., in practice 3°C (to avoid growing snow) to 25°C

* T: 0-above room temp., in practice 3°C (to avoid growing snow) to 25°C

However, it was found that the peaks were very indistinct by at bias voltages below 20V and temperatures above 20°C. This

However, it was found that the peaks were very indistinct by at bias voltages below 20V and temperatures above 20°C. This was probably due to the narrowing of the peaks due to smaller gain or convolution of the additional dark counts detected. The solution to this was to abandon the manual location of pedestals, peak spacing etc. Instead, a model was created by Prof. Richard Jones based on which fitting of the histograms was performed.
