For the correction of N/Q/H errors in phenix.refine: is this option binary (that is, can it only be turned on or off)? Or can it be adjusted to be on but its stringency adjusted to an arbitrary scale?

https://phenix-online.org/documentation/reference/refinement.html#id19 <--suggests its binary, but asking here for thoroughness.

Sincerely,

Nicholas Gao
