What values do you guys generally use for the level, sigma, quantity sliders?  I'm sure it is largely independent to the data set you are specifically using but are there any rough estimates you guys could suggest?

Hi mmarsie,
To define the right value I open a subframe, open Cosmetic correction process, load dark master, enable hot and/or cold pixels, click in the real time preview at the bottom and move to QTY slider looking the real time preview window how bad pixels are corrected, and for potential artifacts, when I'm happy with the results I get this value and load the target frame with the add files  and apply to all the subframes.
