I found it most interesting to see the scientific process in action. Scientists were questioning scientists, sometimes fairly aggressively.
My ideas about astronomy has changed significantly, thanks to NITARP. Quite simply, I didn't understand the role of archival data in modern astronomical research. Previously, I considered it an intellectual exercise, work suitable for a reference librarian, but not real research. I now know it to comprise the future of astronomy, and the very picture of MOST of tomorrow's scientific research.
I did not anticipate how much the astronomers would trust us right away. I felt more like a colleague than a student, which was relieving (and maybe a bit stressful, because I probably would have found it easier to ask questions coming from a student role).
