About the GCN/TAN
- A Brief Description
There are two parts to the GRB Coordinates Network (GCN) (TAN: Transient Astronomy Network):
(1) the real-time (and near real-time) distribution of GRB locations, images, spectra, & lightcurves,
(in < 2sec inside GCN) detected by various spacecraft (Swift, Fermi, MAXI, INTEGRAL, IPN, etc), and
(2) the distribution of follow-up observation reports submitted by the GRB/transient community.
- INVITATION to Join/Subscribe (Notices & Circulars)
An open invitation for GRB researchers and institutions to join GCN/TAN.
For people wishing to receive the GCN/TAN Notices, the required pieces
of information to set up an entry in the "sites.cfg" file are listed.
And for those individuals wanting to receive/submit GCN Circulars, those requirements
are also listed.
- Scientific Motivation and General Background Information on GRBs
