Table 1.

Allometrically scaled parameters are computed as X=Xc*AS, where Xc is a fixed scaling coefficient defined for the parameter in question and AS is the allometrically adjusted body weight used for that parameter. Scaling coefficient values (Xc) and body weight (BW) are provided by the user in input files.
