Radio Afterglow Data (1997-2006)


Welcome. This is a Web page summarizing all radio afterglow data collected as part of a long-standing GRB program at NRAO. The data are divided into two tables. The first table lists GRBs that occurred between 2002 and 2006. Observations of some of these GRBs are still on-going. If you want an ASCII version of the data for a particular burst, just click on its name. The entries in this file (from left to right) are the GRB name, the radio telescope used to carry out the observation, the UT date of the observation (usually taken at the midpoint of the integration), the time since the burst, the observing frequency, the flux density, the rms noise, and a reference noting where the data were published. For those cases where no flux density measurements were made, the flux density column contains "-99".

The second Table is a summary of the data taken from the Frail et al. (2003) paper which presents a catalog of 75 gamma-ray bursts between 1997 and 2001, for which a radio afterglow search was carried out. The full list of telescopes and references (listed here in shorthand) is given in Frail et al. (2003). The ASCII file for all 75 bursts can be found here.

Please Note: These data are placed on this Web site for the convenience of GRB researchers. When using any of this data in your work, we ask that you cite the original references and not this Web address.

(a) From left to right, the columns are the GRB name, the instrument used for the initial localization, the UT time of the burst, the best available position rounded to the nearest arcsecond, and notes on whether an X-ray (XT), optical (OT), or radio (RT) afterglow was detected, based on information gathered from the literature or the GRB Coordinates Network (GCN). A detection is indicated by ``y'', a non-detection by ``n'', and an ``x'' is used when there are no published reports of an afterglow search being made. A ``?'' is used if it is unclear whether an afterglow was detected. Note: this table has been deliberately styled in the format of Jochen Greiner's popular GRB Web table.

(b) BSAX=BeppoSAX, IPN=Interplanetary Network, ASM=All-Sky Monitor and Proportional Counter Array for the Rossi X-Ray Timing Experiment, PCA=Proportional Counter Array for the Rossi X-Ray Timing Experiment, and HETE= High Energy Transient Experiment.

(a) From left to right, the columns are the GRB name, the instrument used for the initial localization, the UT time of the burst, the best available position rounded to the nearest arcsecond, and notes on whether an X-ray (XT), optical (OT), or radio (RT) afterglow was detected, based on information gathered from the literature or the GRB Coordinates Network (GCN). A detection is indicated by ``y'', a non-detection by ``n'', and an ``x'' is used when there are no published reports of an afterglow search being made. Note: this table has been deliberately styled in the format of Jochen Greiner's popular GRB Web table.

(b) BSAX=BeppoSAX, IPN=Interplanetary Network, ASM=All-Sky Monitor and Proportional Counter Array for the Rossi X-Ray Timing Experiment, PCA=Proportional Counter Array for the Rossi X-Ray Timing Experiment, and HETE= High Energy Transient Experiment.
