03.19.2013: Sixth analysis of run 001 - Extension

Here, we have computed the usual diagnostics in the Z0 and Rm space without viruses. Figs. 1 and 2 have to be compared with Figs. 1 and 4 in this note.

We see that:

1. The pattern in the max of Ps and in the max of Z, its timing and final Z have not changed much from the case with viruses
2. The main difference is found at low Rm. For these values of Rm, the Z population is not sustained (with or without viruses) and Ps can go to its maximum value 1 without viruses. This also explains why the timing of the max of Ps is low with viruses (Ps peaks at the beginning before collapsing because of viruses) while it is large without viruses (Ps reaches its maximum value asymptotically). That is a big change with the case with viruses where the final Ps is relatively low (and this final value depends on β, the efficiency of infection, among other things).

Figure 2: Maximum value of Z and its timing, and the final value of Z.

To produce Figs. 1 and 2, manyruns_6.py in RESEARCH/MODELISATION/marine_viruses/current_version/runs/run_001 has been used and were plotted with plot_analysis_many_runs_6.py in RESEARCH/MODELISATION/marine_viruses/current_version/runs/run_001/analysis/manyruns_6/. Everything is on the main ipu1 disk.
