At the last group session when solving the 2013 final exam, I wrongly sketched a michelson interferometer instead of a michelson stellar interferometer - which are two different instruments. If this lead to confusion at the exam last friday, this will not count count against your final score. I very much apologize for any possible confusion!
please note that due to the already ongoing final exams this week, there won't be any more lectures for the AST2210 course. However, we will offer two more exercise classes on Thursday, 3.12 and Thursday, 10.12 at 14:15. Please let us know, if you have any special requests.
