KONUS - Venera KONUS 11 & 12 Bursts
The KONUS instrument is described in Mazets, E.P. & Golenetskii, S.V. 1981, Ap. Space Sci., vol. 75, p. 47. The original KONUS 11/12 catalog is in the following three separate articles: Mazets, E.P., and Golenetskii, S.V. 1981, Astrophys. Space Sci., 75, 47.

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.
The HEASARC's KONUS 11/12 catalog of gamma-ray bursts includes the original published source positions and fluences, and derived peak intensities and durations.
Duration of the burst in seconds.
The fluence, i.e, the energy flux integrated over time for the event, of the gamma-ray burst, in the energy range above 30 keV, and in units of ergs per square cm.
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].
Peak intensity of the burst in counts per 1/4 second.
The time that the burst was recorded.
