What is the exposure time of each frame? Also what is the frame width (arc-seconds)?

Typically the exposure time is 30 seconds and the time between frames is 10 minutes. There are variations that are unpredictable (someone wanted to go a touch deeper, or there was a delay in getting to the same place on the sky) but typically those are the standard numbers.
