Thanks again for spending time on this.<BR>

P.S. I think a binary WF-extraction testsuite would be a good idea. If you like, I’ll apply what you’ve shown me to the qc0_mclachlan.par file, and send in the results ...<BR>

(do I have commit privileges for EinsteinAnalysis/Multipole? I suspect I’m doing everything anonymously right now)<BR>

Sounds like the symmetry boundaries are not being applied. Aha! You <BR>
need to set the parameters<BR>
<BR>
WeylScal4::Psi4r_group_bound = "flat"<BR>
WeylScal4::Psi4i_group_bound = "flat"<BR>
<BR>
Have a look at the test suite parameter files for WeylScal4. This is <BR>
not necessary in the current development branch, as this is done <BR>
automatically by Kranc now.<BR>
<BR>
It occurs to me that we could do with an example for the use of <BR>
WeylScal4 and Multipole, e.g. by using WeylScal4 in one of the <BR>
McLachlan QC0 example parameter files.<BR>
