The final value is then estimated by a Poisson fit of collected data. Data File: Path to save the single txt file containing the dark rate per voltage point and per temperature Temperature array: Comma separated temperature values. For each temperature a dark rate scan up to the maximum voltage OR until instrument saturation will be performed. Max Voltage: Maximum value of HV to be tested. Typically sensors saturate dark rate measurement capabilities of the instruments <ul style="display: flex;"><li style="flex:1">before reaching this point.
