From edbba678b3cdc8f06a84a965b04f13ef1f4ecaab Mon Sep 17 00:00:00 2001 From: Dirk Hohndel Date: Fri, 4 Nov 2011 14:25:20 -0700 Subject: [PATCH] Don't repeat redundant minima or maxima in the profile plot If we have more than four identical depth readings, the old code would see those as local maxima and minima and print spurious depth values in the profile plot. Yes, in real sample data identical readings won't happen - but in synthetic data they can and there this looks really bogus.
