TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2298 SUBJECT: GRBlog: Compilation of all GCN Circ. data DATE: 03/07/14 19:07:30 GMT FROM: Robert Quimby at U of Texas/ROTSE Robert Quimby, Erin McMahon, and Jeremy Murphy (U. Texas) write: We have compiled all the optical, radio, and X-ray data reported in the GCN Circulars over the last year (~875 GCNs). The messages have been marked up in HTML, and can be viewed at http://grad40.as.utexas.edu/grblog.php. A search form provided at http://grad40.as.utexas.edu/search.php can be used to select messages, bursts, or data which meet very specific criteria such as to find all GRBs with a 25-100 keV fluence greater than 1e-6 erg/cm^2, and duration longer than 5 seconds that were observed in the R band within 12 hours of the burst trigger, but had no detected afterglow to a limiting magnitude of 19. As an example, plots of each data set for the GRB 030329 afterglow, along with links to the data tables can be found at: grad40.as.utexas.edu/grblog.php?view=data&GRB=030329&datatype=optical grad40.as.utexas.edu/grblog.php?view=data&GRB=030329&datatype=radio grad40.as.utexas.edu/grblog.php?view=data&GRB=030329&datatype=xray The magnitudes of the optical data come directly from their respective GCN Circs. They have not been placed on the same photometric system; however, each reference system is listed in the table. We are currently archiving the remaining GCNs. We hope to have all GCNs entered by early Fall.
