LIGO Document G1201267-v1
- The first generation of gravitational-wave (GW) detectors have reached their initial goals for sensitivity and produced interesting upper limits. While these detectors did not detect a GW, the next generation of detectors are poised to make such detections in the not-too-distant future. Determining source parameters quickly and accurately is useful for the multi-messenger astronomy community and these measured parameters will also likely impact cosmological and population modeling. We will discuss our preliminary investigation, a single case study, on the effects on parameter estimation and source bias when detecting a compact binary coalescence (CBC) signal using two Advanced LIGO (aLIGO) detectors. For that suspected gamma-ray burst source, it appears that the observable source polarization angles are non-uniform across the sky. This bias can be used to speed up parameter studies, and possibly impact source selection of CBC objects in the observable volume of aLIGO detectors. We present our case study and offer motivation on how properly considering these effects on observable source polarizations across the sky may be beneficial to analysis and modeling efforts.
