Survey Parameters

The simulations analyzed here are grouped into 11 ensembles, each containing 8 realizations. One ensemble serves as a reference; the other 10 ensembles are derived by varying parameters including the pericentric separation, disk orientations, and disk velocity dispersion.


The galaxy models used in these experiments have three components:

All simulations have these parameters in common:

The reference ensemble has these parameter values:

Parameter values for all 11 ensembles are:
