TO: All GCN Notice recipients RE: Fermi-GBM Location Maps added DT: 30 Apr 2014 INTRODUCTION: The GCN system has been modified to incorporate the distribution location maps for Fermi-GBM triggers. URL link information has been added to the full-format form of the GBM_FINAL email notices, the 160-byte binary socket packets, and to the various forms of VOEvents. WHICH NOTICES and AVAILABILITY DELAY: These location map URLs are included in the notice types listed in the table below: TYPE PKT_NUM DELAY [min] ================== ======= =========== GBM_FIN_POS 115 1-15 min where the "DELAY" is the time between the issuing of the FINAL notice type and the availability of the location map product. THE LOCATION MAP URL: The url included in the email is of the form: http://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/20YY/bnYYMMDDFFF/quicklook/glg_locplot_all_bnYYMMDDFFF.png and here is a real example (the YY, YYMMDDFFF parts have been replaced with real values): http://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2014/bn140405033/quicklook/glg_locplot_all_bn140405033.png Once this string is built, then you can use the 'wget' command (or similar) to retrieve the location map file: wget http://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2014/bn140405033/quicklook/glg_locplot_all_bn140405033.png OTHER LOCATION MAP DATA IS ALSO AVAILABLE: The 1,2,3-sigma contours shown in the png file are also available in text form: http://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2014/bn140405033/quicklook/glg_locplot_all_bn140405033.txt It contains RA,Dec pairs sampled along the 3 contours. This text form of the location map is more appropriate for robotic operations to construct a series of tiling observations on the sky. There is also a readme file explaining the contents of these 2 data products: http://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/20YY/bnYYMMDDFFF/quicklook/README ACTION ITEM: There is no action needed on your part. If you are already receiving the Fermi-GBM_FINAL notice type, then the location map link information is already included in what you are receiving. (Of course, you can always change your configuration to enable or disable any of these Fermi-GBM notice types. And you can make any other changes to your configuration.)
