TO: All GCN Notice recipients RE: AMON IceCube HESE Notice type is available DT: 08 April 2016 INTRODUCTION: The GCN system has been modified to incorporate the distribution of candidate coincidence events produced within a single instrument and/or between multiple instruments within the AMON project. Currently, only HESE (High Energy Starting Event) notices within the IceCube instrument are being produced. This will expand to include the AMON_ICECUBE_COINC type and others in the future. Like all the other sources of transient information within the GCN system, users can elect to receive this AMON_ICECUBE_HESE Notice type. OCCURRENCE RATE: There will be about 4 AMON_ICECUBE_HESE Notices per year. TIME DELAY: The time delays for this notice type will range from 0.5 to 3 minutes after the neutrino interacts in the IceCube detector. LOCATION ERROR: The location uncertainties are in the 2-9 deg range (radius, stat+sys, 90% containment). The uncertainty in the location will depend on: (a) the energy of the neutrino, and (b) the track-vs-cascade nature of the energy deposited in IceCube. NOTICE TYPE, CONTENT, and PURPOSE: In this initial release, there is only one AMON notice type (ie ICECUBE_HESE; there will be more in the future). The AMON_ICECUBE_HESE is the result of IceCube detecting a single high-energy neutrino in their detector with a good track-like deposition (ie not cascade-like). These can be caused by Supernova, GRBs, other astrophysical transients, and sometimes background. The Notices contain the date, time, and trigger number, the amount of charge deposited in the PMTs, and false_positive probability and the p-value probability. It contains the RA,Dec location of the direction that this single high-energy neutrino came from.
