developed by Buehlmann.
Arguments
format
A data frame giving the following parameters for each compartment:
ll{
id compartment name (1, 1b, 2, ..., 16)
halftime Nitrogen halftime (minutes)
a parameter $a$ in ata (atmospheres absolute)
b parameter $b$ (dimensionless)
}

Details
Buehlmann's decompression model ZH-L16A is a pure
diffusion (Haldane-type) model consisting of 17 tissue compartments.
Nitrogen in the breathing gas diffuses in and out of each compartment
at a rate governed by the halftime for that compartment.
The maximum tolerable nitrogen tension in a compartment,
when the ambient pressure is $P$ atmospheres absolute,
is
$$P_{\mbox{tol}} = a + \frac{P}{b}$$
where $a$ and $b$ are values intrinsic to the tissue.
Thus, for a no-decompression dive at sea level, the nitrogen tension
in each compartment must not exceed the value $a + 1/b$ for
that compartment.
