DESCRIPTION

Tempo is a program for analyzing pulsar timing data.  Pulse times
of arrival (TOAs), pulsar model parameters, and coded instructions
are read from one or more input files.  The TOAs are fitted by a
pulse timing model incorporating transformation to the
solar-system barycenter, pulsar rotation and spin-down and, where
necessary, one of several binary models.  Program output includes
parameter values and uncertainties, residual pulse arrival times,
chi-squared statistics, and the covariance matrix of the model.

In prediction mode, ephemerides of pulse phase behavior (in the
form of polynomial expansions) are calculated from input timing
models.
