# The Pioneer Venus Orbiter Catalog of Gamma-Ray Bursts

## TL;DR

This paper presents a catalog of 318 gamma-ray bursts detected by the Pioneer Venus Orbiter over 14 years, providing valuable data on bright gamma-ray bursts and constraining their distribution slope.

## Contribution

It offers a comprehensive catalog of bright gamma-ray bursts and constrains the bright end slope of their Log N-Log P distribution, complementing existing datasets.

## Key findings

- Detected 318 gamma-ray bursts over 14 years.
- Constrained the bright end slope of the Log N-Log P distribution to -1.52±0.15.
- Provides data that complements BATSE observations.

## Abstract

The Pioneer Venus Orbiter (PVO) Gamma-ray burst experiment detected 318 gamma-ray bursts over about 14 years between 1978 and 1992 with near $4\pi$ coverage. This data set complements BATSE by determining the properties of the brightest gamma-ray bursts. PVO places a constrains on the slope of the bright end of the Log N-Log P distribution. The slope is -1.52$\pm 0.15$.
