From 95720e94eee79abd64dcc16969ad6b91d7c1ae50 Mon Sep 17 00:00:00 2001 From: Rick Walsh Date: Wed, 16 Sep 2015 19:57:24 +1000 Subject: VPMB gradient of imperm: don't confuse atm and bar Other VPM-B implementations (V-Planner, MultiDeco, Fortran code) take the default gradient of onset of impermeability as 8.2 atm. We use bar as the pressure unit, and 8.2 atm = 8.30865 bar. This has negligible effect on all of the calculated plans I've tested, resulting in a maximum decrease of 1 minute in total dive time for ~150 m deep dives, but we should get unit conversions correct anyway.
