TEMPO2: a New Pulsar Timing Package

Abstract

TEMPO2 is a new pulsar timing package that provides the precision necessary for modern millisecond timing projects and should supersede all existing pulsar timing packages such as TEMPO and PSRTIME. As TEMPO2 is the only program available that can analyse multiple pulsar datasets simultaneously it will become an integral part of pulsar timing array projects which aim to detect the signatures of gravitational radiation in pulsar timing residu-als. In this paper we describe the basic functionality of TEMPO2.
