2500 images - Infinite process

Wishgranter: “the reprojection error does not need to be ultra-low … everything under or slightly over 0,5 pix is OK”

Manuel: “… setting the reprojection error to 2.0 (which equals to 0,5pix?)”

Is that correct - reprojection error is reciprocal of ‘pix’?

Or is the 0.5pix mentioned by Wishgranter actually the mean and median error in Alignment Report?
