(2) "initial conditions" for that orbit (orbital inclination and ascending mode)
(3) to plot ground track through a given "rectangle," 
(a) write eq'ns for boundaries (in terms of theta and phi)
(b) ask if theta_min < theta < theta_max and phi_min < phi < phi_max
(c) no? lift pen go to (e)
(d) yes on last pass?
yes - move with pen down to this point
no - move to point with pen up, put pen down
(e) go to next point
