Parameters for the basic and extended models.

?EB = Elementary Body; ?Ab = Antibody.Parameters included in the extended model are indicated by (*). Parameters with (��) have been scaled to be dimensionless with respect to state variables. Scaling was based on an arbitrarily select reference category. State variable reference categories (yref, eref, zref, and uref) were the peak values (or lowest, for xref) at initial infection.
