Fig. A.1.


Correlation matrix of the three-component maximum-likelihood fit with SPI in the energy bin 1795.0–1795.5 keV. The background component continuum and lines have been re-scaled 29 times each, corresponding to the time between two annealing periods (or detector failure and annealing period). The individual blocks are further explained in Figs. A.2a–A.2c.
