Parameters values that were not obtained from literature were chosen to be in the ranges 0 to 1. Est. means parameters were estimated/derived to simulate acceptable HIV dynamics. The infectivity of the cell associated virus is 10² to 10³ times greater than the infectivity of free virus stocks [14], so we multiplied the infectivity of the free virus by values in the ranges 10² to 10³ to get the infectivity of the cell associated virus.
