In the top right hand corner of page 8 is a graph of the characteristic curve showing three plots; all labeled "PL Q."
Can someone please identify the metric "PL Q?"
Thanks!
Edit: I'm guessing it was an error not caught during the accuracy check prior to publication unless "PL Q" actually does signify something.
Tim Gary's excellent 125px site has a bunch of historical Kodak technical documents preserved there. The 2007 version of 4016 lists three times in the place where those place-holders reside - 10 min, 7.5 min, 6 min
