Description

In the ECHo experiment, the effective electron neutrino mass can be determined by the analysis of the endpoint region of the calorimetrically acquired $^{163}$Ho electron capture spectrum. The spectrum was acquired using arrays of tens of low temperature metallic magnetic calorimeters enclosing the source. The fraction of $^{163}$Ho events which are in the region of interest can be as small as $10^{-9}$. To separate this small fraction from spurious events generated by noise and interference, a data reduction structure has been developed with minimal and well-characterized energy dependence. The data acquired for the ECHo-1k experiment has been reduced and a partial histogram has been constructed after gain correction and calibration for each single pixel and for an acquisition time of about two days. A quality check protocol was developed to classify the single data files and select those to include in the final high statistics spectrum.
We describe the data analysis structure, the efficiency of the single filters and construction of the high statistics spectrum with the files selected after quality check.
