Exposure targetting: ValueError: cannot convert float NaN to integer

Added by Amedee des Georges over 10 years ago

Hello,

I got this error message as leginon tried to run exposure targetting over a gridbar. It then got stuck there, unable to proceed to the next hole.

Looks like the scaling failed to catch the fact that K2 counting gives back min = max = 0. I will look for a fix.
