I should have divided the 200 feet by the sine of the angle of elevation (21.5 degrees), to get the ground distance; that would give about 550 feet to the closest point on the center line, and mean that the MCC prediction was off by about 500 feet, or about half of the OIG error. For a high elevation pass (e.g., at a range of 270 miles), the ISS's solar panels would be about 40 seconds of arc across; the MCC error would have been about 30", versus 60" for the OIG prediction. ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
