TITLE: GCN CIRCULAR NUMBER: 22080 SUBJECT: GRB 171030A: IPN error box through NSs probability merging rate map DATE: 17/11/02 08:17:37 GMT FROM: Vladimir Lipunov at Moscow State U/Krylov Obs V. Lipunov, Lomonosov Moscow State University, Sternberg Astronomical Institute, Moscow State University D.Svinkin Ioffe Institute, St Petersburg E. Gorbovskoy, N.Tyurina, D.Kuvshinov Lomonosov Moscow State University, Sternberg Astronomical Institute, Moscow State University We present NSs merging rate MAP inside local 50 Mpc distance (see Lipunov, V. M.; Nazin, S. N.; Panchenko, I. E.; Postnov, K. A.; Prokhorov, M. E. The gravitational wave sky, Astronomy and Astrophysics, v.298, p.677, 1995; Lipunov et al., 2017, https://arxiv.org/ftp/arxiv/papers/1710/1710.05911.pdf ). There are two common regions belong to IPN (Kozlova et al., GCN 22076) (black on picture) aproximated next rectangle: First: [37,-35] [60,-20] [60,-30] [40,-45] Second: [73,-10] [80,-04] [80,-11] [73,-21] Maps are available at http://observ.pereplet.ru/images/VLNSmergrate.jpg The possible Swift localisation () is shown by green square. Common IPN + NSsMerging probability Map region are available http://observ.pereplet.ru/images/GRB171030A_1.txt http://observ.pereplet.ru/images/GRB171030A_2.txt The message may be cited.
