Fitting Results for Co-57 Runs

Double-MuTau Model

Here, we develop a new spectral model composed of two "mutau-model"s. One has high mutau-hole and the other has low mutau-hole. The two have also different normalization parameters, the ratio of which corresonds to the fraction of the number of detectors with the different mutau hole parameters.

EXT NO.PARAMETER NAMEDescription
1VoltageBias voltage, which is constant usually at the nominal operation voltage of 200V.
2MuTau_EMobility-Lifetime (mu*tau) product for electron, which is fixed to 1.0e-03 cm^2/V.
3MuTau_H_1Mobility-Lifetime (mu*tau) product for hole.
4MuTau_H_2Mobility-Lifetime (mu*tau) product for hole.
5SigmaElectronic noise in the unit of channel (1 channel corresponds to 0.25 keV), excluding the low-energy tail effect.
6GainGain parameter in the unit of channel/keV. This represents the gain for the "ch_max", that is, a peak position when charges are fully collected.
7Norm_1Normarization 1 in the unit of photons/cm^2.
8Norm_2Normarization 2 in the unit of photons/cm^2.
