The contour plots in Figure 6 were created using the functional dependence of the plaque velocity and viral titer growth rate on the infecting time, t inf , and the latent infection period, t L , as determined by model simulation, along with the experimentally measured values of these quantities and their associated measurement error, under the assumption that these errors are normallydistributed. For example, the function F v , plotted in Figure 6A and Figure 6D , takes values between zero and one, according to
