  : Estimates of the percentage of flares expected to be observed \[${e}$\] by each instrument based on the product of their duty cycles and field-of-view. The calculation assumes that each instrument points randomly in the area of consideration. The percentage of flares that were actually observed \[${m}$\] is also presented.

[Duty cycle estimated at approximately three hours per day (see text).]{}

[Duty cycle estimated by examining recent EIS planning notes. Field of view estimated at $240''\times 240''$, one quarter the full FOV of EIS.]{}

[Field of view estimated at $200''\times200''$, one quarter the full FOV of SOT.]{}

[Field of view estimated at $1024''\times1024''$, one quarter the full FOV of XRT.]{}

[Field of view estimated at $85''\times85''$, one quarter the full FOV of IRIS.]{}

[Out of the 934 flares listed in the HEK over the 11-month period that all seven instruments were operational. This is around half of all the flares listed in the NOAA/GOES event list (1774).]{}
