Status of the GERDA Experiment at the Laboratori Nazionali del Gran Sasso
Figure 7
(a) shows the background decomposition (black histogram) and the observed spectrum (black dots) using the best fit minimum model for the - data set in the energy range from 570 keV to 1650 keV. The lower panel shows the data over model ratio (empty points) and the smallest intervals containing 68% (green), 95% (yellow), and 99.9% (red) probability for the model expectation. (b) shows the same for the energy range from 1650 keV to 3750 keV. From [28].
