I wish I could say I used some kind of crazy NASA pico arcsecond-resolution measurement gizmo to calibrate the angular values I plugged into terminal.c. To be honest, at about 8:30 PM the night before the kick-off (last Friday), I finished the code and did a half-arsed calibration using my eight-year-old son's cheezy protractor. Using the equation found in terminal.c, I would do another calibration <grin>.
