This research has made use of data, software and/or web tools obtained from the Gravitational Wave Open Science Center (https://www.gw-openscience.org), a service of LIGO Laboratory, the LIGO Scientific Collaboration and the Virgo Collaboration. LIGO is funded by the U.S. National Science Foundation. Virgo is funded by the French Centre National de Recherche Scientifique (CNRS), the Italian Istituto Nazionale della Fisica Nucleare (INFN) and the Dutch Nikhef, with contributions by Polish and Hungarian institutes. MI is supported by NASA through the NASA Hubble Fellowship grants No.\ HST-HF2-51410.001-A awarded by the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., for NASA, under contract NAS5-26555.

Posterior samples for the LIGO-Virgo gravitational wave signal GW190521 conditional on the location of AGN J1249+3449. This dataset contains a file with results fixing the sky location to J1249+3449 (posterior_samples_GW190521_J1249+3449.h5), and another additionally fixing the luminosity distance to 2511 Mpc (posterior_samples_GW190521_J1249+3449_2511Mpc.h5). These analyses are motivated by Graham et al 2020. The posteriors were sampled using LALInference (Veitch et al 2015) with the same configuration as in the LIGO-Virgo analyses (Abbott et al 2020 PRL and Abbott et al 2020 ApJL). The results were packaged using PESummary. For instructions on how to load the result files, please see the PESummary documentation.
