Thank you for this! I need to use McLachlan and z-axis symmetry for now, but your parameter file will be very useful starting place, and I'll definitely want to use BaikalVacuum later too.</div>

<div>Hi Rhiannon,</div>
<div><br>
</div>
<div>I released a set of GW150914 parameter files that forego use of Llama and use BaikalVacuum for the spacetime evolution, as part of my paper <a href="https://arxiv.org/abs/2404.01137" originalsrc="https://arxiv.org/abs/2404.01137" target="_blank">https://arxiv.org/abs/2404.01137</a>
. The parfile can be found here:<br>

I need a parameter file similar to the GW150914 binary black hole example but <b>
without</b> the Llama patches. Does anyone already have something like that I could use? If not, would it be a good idea for me to start from the qc0-mclachlan example and adapt that to my needs?
<span style="font-size:16px">It seems like that might be easier than trying to work backward from GW150914.par?
</span>Is there anything old/outdated in the qc0-mclachlan example which I should be aware of? </div>

Also, can anyone tell me why qc0-mclachlan uses 3 refinement centres (CarpetRegrid2::num_centres = 3) and not<span style="font-size:16px"> 2 as in GW150914?</span></div>
