Status of the GERDA Experiment at the Laboratori Nazionali del Gran Sasso
Figure 3
(a) shows the experimental data (black markers) and the best fit model (black histogram) for the sum of the semicoaxial detectors in linear scale and (b) in logarithmic scale. Individual components are shown with colored histograms. The shaded band covers the 68% probability range for the model expectation. (c) gives the ratio between experimental data and the prediction of the best fit model. The smallest intervals containing the 68%, 95%, and 99.9% probability for the expectation are shown in green, yellow, and red regions, respectively. From [31].
