Draft: Combine science changes for MDC test

Just making a merge request as a convenient way to share these combined changes.

I should probably be using some other tool to produce a nice sharable diff.

Combines !100, !101.

It includes:

• remove 1.414 (still requires sqrt(pklist->cohsnr[peak_cur]) > pklist->snglsnr[ifo_id][peak_cur], though as I understand that's basically redundant since cohsnr ~= sqrt(snr_H1^2 + snr_L1^2 + ...)
• Add 0.3 min chisq threshold in postcohkernel for an IFO to contribute to cmbchisq (foregrounds and backgrounds)
• Remove superevent threshold (previously anything below this far doesn't go through additional thresholds/checks)
• finalsink only requires 1 significant IFO per trigger, but it needs: postcoh_inspiral.snglsnr[ifo_id] >= 4.0 , postcoh_inspiral.chisq[ifo_id] < 3.0, postcoh_inspiral.chisq[ifo_id] >= 0.4, postcoh_inspiral.far_sngl[ifo_id] > 0.0, postcoh_inspiral.far_sngl[ifo_id] < self.singlefar_veto_thresh
• Fixes reduced chisq calculation (sum(chisq)/sum(autocorrnorm) instead of sum(chisq/autocorrnorm)/num_detectors
  • i.e. reduced cmb chisq vs sum(reduced single chisq) / num_detectors
