The other two options visible on the screen are solve and quit.
Solve may be selected by moving the highlighting bar until it is over solve and then pressing the Enter key, or by pressing the letter `s'. This begins the calculation of the 
-
coverage tracks using the
parameters as they are currently shown on the screen. During the calculation,
the initial screen is erased and the allsky plot is drawn using the
entire available screen. The fraction of the observing time for which
calculations are complete for each - coverage plot is
displayed on a scale at the bottom of the screen.
The quit option may be selected by using the highlighting bar or by
pressing the `q' key. This option is used to leave the program once the
user is finished.
See Figure 
on p. for a completed run of
allsky.
