Super Bias yielding vertical Lines
« on: 2019 October 18 16:49:48 »
I'm a newbie to PI.  When I produce a super bias from an integrated bias from 40 frames, the process produces a dense frame of vertical lines.  The integrated bias and super bias can be seen here:  Where are the vertical lines coming from?  Thanks in advance.

that's what a superbias looks like - the idea is that all the noise has been removed and you are left with the pure bias values.
