is therefore the product of the duty cycle and the FOV. This can be readily compared to the measured success rate \[${m}$\] for each instrument individually from the 11-month period during which all seven instruments were operational together. This time period also happened to coincide with the peak of the solar cycle as illustrated in Figure \[solar\_cycle\]. These expected and measured values are presented in the last two columns of Table \[tab:estimated\_flares\]. The success rates over this 11-month period bear a reasonable agreement with the values measured over the entire 6.5 years under study that are presented in the final column of Table \[tab:instr\_flares\], and they can therefore be considered as characteristic of each instrument. They are also consistent with or better than the individual expected value implying that each pointing instrument is performing well. This reflects the fact that solar flares are a high priority science goal for these instruments, and that operators of course do not point their instruments randomly.

The measured success rates of each individual instrument in Table \[tab:estimated\_flares\] can be used to predict the number of flares expected to be seen by different combinations of instruments as follows. The measured success rate of each instrument
