TITLE: GCN CIRCULAR NUMBER: 1519 SUBJECT: GRB020813, Baade 6.5m data now available DATE: 02/08/23 03:21:24 GMT FROM: Mike Gladders at Carnegie Obs. Mike Gladders (Carnegie Observatories) and Pat Hall (Princeton/Catolica): On the basis of previous experience with the public release of GRB data taken by us at LCO (GCN #1209), we have decided to release the Baade 6.5m (Magellan I) data taken of GRB 020813 on the nights of August 13 and 14 UT for general use by the community. We anticipate that this high-quality data, which provides several hours of early photometry of the burst under sub 0".5 seeing conditions, will be of use to a number of researchers. As before, we anticipate that appropriate collaboration(s) will evolve as circumstances dictate. Meanwhile, the pre-processed data, including a README file detailing observing conditions and preliminary zeropoints for the images, can be downloaded by anonymous ftp from: ftp.ociw.edu pub/gladders/GRB/GRB020813 Raw science frames, as well as extensive calibration data can be provided if necessary; please contact Mike Gladders (gladders@ociw.edu) to arrange for this.
