Hi all.
I was post-processing a BHB merger run, and noticed a problem with my waveforms, extracted using WeylScal4 and Multipole: the (2,2) mode looks fine, but the (2,-2) mode is highly suppressed (by about an order of magnitude). Ditto the (3,+/-3) modes etc, though the amplitude mismatch is different for each (l,m) case.
I thought I was post-processing incorrectly, but the problem is in the "mp_psi4_lX_mY_rZ.asc" files. The negative-m data is also considerably noisier than the positive-m data.
I assume I'm missing something in my parameter file. Some subtle (or not-too-subtle) symmetry setting relevant to Multipole. Can someone help, please? I'm attaching my parameter file. It's adapted from the ETK BBHLowRes.par file (and a brief run of that appears to have the same issues for me).
I'm using Maxwell, by the way. Any help appreciated.
Bernard
