Table 3: The scaling ratio of the >10 keV count rates outside (Col. 2) and inside (Col. 3) the telescope FOV in the background template files compared to the cluster files. The former ratio is an indication of the particle (cosmic ray) background rate, while the latter indicates the level of the soft proton background rate. These ratios are plotted as a function of Julian date in Fig. 4.
