The fault data base allows a more detailed overview of the faults that are reported. In Table 2 the number of faults and total time lost as a function of the system and kind of fault is presented together with the overall numbers for the last period (28).

One conclusion that can be drawn from the information in Table 2 is that beyond the problem with the filter wheel in NOTCam there were no other significant problems causing downtime.
