[Users] 8th vs 6th order

Hi,

The GW150914 example parameter file uses 8th order finite differencing and I need a 6th order version for comparison in terms of both accuracy and speed. Apart from changing the finite differencing orders from 8 to 6, and I assume GlobalDerivative automatically selects the correct dissipation order since it's not specified, what would I use for the following values?

Driver::ghost_size = 5 Coordinates::patch_boundary_size = 5 Coordinates::additional_overlap_size = 3 Coordinates::outer_boundary_size = 5

Carpet::prolongation_order_space = 5

Is there anything else I missed that I should change?

Thank you, Rhiannon.
