A catalog of HEALPix all-sky maps produced as part of the
Burst First2Years localization characterization study.
This includes both the 2015 (LHO-LLO) two-detector network and the 2016 (LHO-LLO-Virgo) three-detector network, for all four morphologies considered:
sine-Gaussians (SG), Gaussians (G), White-noise Bursts (WNB), and Binary Black Holes (BBH).
We compare two localization algorithms, coherent WaveBurst (cWB) and LALInferenceBurst (LIB) over a set of astrophysically distributed injections detected by cWB. These injections cover a broad range of morpholgies and probe very different frequency ranges and content. In particular, we discuss how signal morphology affect localization with examples taken from our data set. We also include typical localization results, focusing in the "searched area" as our main quantitative description.

We provide the full lists of detected injections as well as associated skymaps and injection parameters as part of the catalogs. Please browse through our thumbnail galleries (2015, 2016) or download tarballs below and investigate the FITS files yourself.
