KONUS: Konus 11 & 12 Gamma-ray Burst Catalog

Overview

KONUS Gamma Ray Spectrometers

The KONUS instruments were flown on pairs of Venera spacecraft. Veneras 11/12 were launched in September 1978; bursts were recorded through January 1980. Veneras 13/14 were launched in November 1981 and were operational through approximately March 1983. The Veneras were interplanetary spacecraft, which flew to Venus, and thus each spacecraft had whole sky coverage for most of its mission.

Instrument Information

The KONUS instrument was designed to have quasi-omnidirectional response to bursts. The instrument consisted of six NaI(Tl) crystals, each 4 cm radius X 3 cm depth, arranged on the three orthogonal space axes. The cylindrical side of each detector was shielded with lead and tin, with the back side faced with heavy lead glass and viewed by a photomultiplier tube. Each detector then preferentially saw photons arriving from the forward direction. The spacecraft operated in two modes, spin-stabilized and triaxially stabilized. In the latter mode, the angularly dependent responses of three detectors afforded coarse (nominal uncertainties of ~ 5 deg), one-spacecraft localizations. The former mode required detection by KONUS instruments on both Veneras, the resultant localization being the intersection of two annuli.

The burst spectra were recorded in 16 quasi-logarithmically spaced energy channels spanning the range 30 keV to 2 MeV. Temporal resolution was 1/64 s for the first 2 s, 1/4 for the next 32 s, decreasing to 1 s for the remainder of the 66 s record. Burst trigger integration times were 0.3 s and 1.5 s.

Konus 11 & 12 Burst Catalog

There are five columns in the catlog -

  1. Name: The gamma-ray burst identification (i.e., name) consists of the date and, if there were two bursts on the same date, a letter "a" or "b" to indicate which occurred first on that date. The format for the name is yr.mm.dd[id].
  2. Time: The time that the burst was recorded.
  3. Fluence: The energy flux.
  4. Peak_Intensity: Peak intensity of the burst in counts per 1/4 second.
  5. Duration: Duration of the burst in seconds.
