-* Use small domain, with Vs floor of 500 m/s (CVMS4.26-M01 (cmvsi)) and constraints, [https://scec.usc.edu/scecpedia/HighF_2018#Mesh_generation_rules_and_parameter_constraints as described here]

-* We agreed that all the modelers will use a version of the small domain that is rotated by 39.9 degrees, so as to remove a source of difference we can control. We observed different results due to rotation of the domain in CyberShake simulations a few months ago, for which we could not account for by considering the model edges and boundary effects. There seems to be some anisotropy in the model that may be due to the staggered grid.
