What tables/algorithm does Baltic use ?

Baltic implements VPM/B and ZHL16 with Gradient Factors.

What ZHL16 values are used ?

The halftimes used (0.9 and upwards) are ;

  • N2: 4, 8, 12.5, 18.5, 27, 38.3, 54.3, 77, 109, 146, 187, 239, 305, 390, 498, 635
  • He: 1.88, 3.02, 4.72, 6.99, 10.21, 14.48, 20.53, 29.11, 41.20, 55.19, 70.69, 90.34, 115.29, 147.42, 188.24, 240.03

Where did the algorithm implementations come from ?

Both were implemented for another project in 2007 and 2008 respectively. The ZHL16 implementation is based on available litterature, such as Dr. Bühlmann's Tauchmedizin, and Dr. Wienke's "Technical Diving in Depth".

The VPM/B implementation is a reimplementation of Erik C. Baker's reference fortran implementation.
