78 Define model dimensions.
79 NUM_COMP is the number of compartiments in the Bühlmann ZH-L16 model, ie 16.
80 NUM_STOPS is the maximum number of stops computed by decoplanning.
81 Note that the deapest stop is roughly limited to 3m * NUM_STOPS
82 (this is assuming all stops up to the surface are used).
83 Note also that if the table overflow, extra stops are ignored,
84 and not reported in TTS summing.
85 NUM_GAS is the number of (potentially) active gas considered during
86 ascent simulation.
