comparison code_part1/OSTC_code_c_part2/p2_deco.c @ 212:275befc5f39d

Debug GF model (bug #11 & #12). + ASSERT stops should be computed in order (bug#11). + BUGFIX: Mark GF_low reference at actual first stop, not predicted one. + BUGFIX: sim_to_first_stop() stops BEFORE first stop, not after (bug#11). + BUGFIX: check that calc_nextdecodepth() don't ascent faster than 10m/mn (bug#11). + BUGFIX: calc_nextdecodepth() should check gas switch, too (bug#11). + let gas switch detection in depth/meter (not ambientPresure/mbar). + BUGFIX OCR mode: bad diluent value in sim_alveolar_pressure() (bug#11). + BUGFIX: add deco distance (offset) only to compartiment integration, not to B?hlmann or GF criterion. + BUGFIX: add margin one meter above gas switch depth (bug#12) + BUGFIX: When ascenting too fast, cancel gas switch delay and history (bug#11).
