David,
The easiest way is to run the WinListen program, which is one of the auxiliary programs which is installed. Start it up, pick the source of Keps and the satellite, time span and time step of interest, and then tick Rising and Setting. You will note that the beginning and ending elevation usually is not exactly zero if you take the default step. Pick something smaller, 10 seconds or so, and it will be very close. There is an WinAOS program which gives related data in a slightly different format. Hopes this helps.
