[Ifeffit] This might be a silly question....

Hi, I'm also a novice with the Athena/Artemis Ifeffit software. I've read through the online documentation for both and I'm now trying to go through the Cu example in Chapter 2 of the Artemis manual. Can someone please tell me where I input the following information into Artemis (I've tried in the fields on the Path parameter screen, but it gives me an error when I go to fit)? (from page 19 of the manual): We will then define extremely simple math exressions for the corresponding path parameters of the first shell. s02 0:1 amp e0 0:1 e0 delr 0:1 delr sigma2 0:1 ss Thanks, Kristine Witkowski Northwestern University
