* clusters/main.py: Implement "_simulate_merger()"Aaron LI2017-07-202-15/+95
| | | | | | | | | | Simulate the formation history of each cluster and identify the last/recent major merger event. Also add new configuration option "tau_merger" and tweak several configurations options. Signed-off-by: Aaron LI <aly@aaronly.me>
* clusters/formation.py: show verbose info only in DEBUGAaron LI2017-07-201-6/+9
| | | | | | | | Since the ``ClusterFormation`` is repeatedly invoked in ``GalaxyClusters``, so make the verbose information printed only at DEBUG level. Signed-off-by: Aaron LI <aly@aaronly.me>
