You are expected to check for new announcements every day.
Dated announcements are periodically moved to the archives.
May 13 Final exam solutions and course grading guide are here.
May 11. Grading of the Take-Home is progressing, but slow. Here are the test scripts that I am using for problems 1, 2, and 3.
May 11. You will find solutions to the study questions in here and there..
May 7: The review session will be in Upson 111. Check out the problems of the day for further review questions.
May 1: Review session Friday, May 8, 4:45-6:00. Location TBA. Some study questions. More to follow
April 30. Notes on the take-home:
P1: The input and output lats and longs should be in radians.
P2: You must supply an analytic gradient--not a divided diff approx.
P3 All the denominators with y'*y + z'*z should be (y'*y)(z'*z).
April 22 Here is a guide for using fsolve.
April 20. Schedule for the rest of the semester:
Wed April 22: Take-Home part of final handed out
Mon May 4: Take-Home part of final due
Tues May 12: In class part of the final, 9-11:30, 253 Malott Hall
Revised Course grading scheme: (Assignments 1-5, 8% each) + Prelim 1 (15%) + Take Home Part of Final (20%) plus in-class part of the final (25%)
April 14 Extra Office Hours Today: 1:30-3:00
April 13 Couple of comments on Assignment 5...
(a) Please use r = 6371 km for the earth radius. (I used r = 3188 in the write-up. The world >>is<< smaller since the 1960's but not that much smaller!)
(b) For the extra credit, get the transit times as accurately as possible--maybe down to the nearest second.
(c) In P2 you are to pay attention to both accuracy and computational cost. I want to leave the trade-off open-ended so that you have to make some choices. Most important is that you briefly discuss the trade-off. Think of P2 as a prelude to doing the same problem with super-accurate orbit models and that your job is to anticipate the cost associated with a given precision of accuracy.
