  We make a very large realisation of a Gaussian white noise field, called
PANPHASIA, public by releasing software that computes this field. Panphasia is
designed specifically for setting up Gaussian initial conditions for
cosmological simulations and resimulations of structure formation. We make
available both software to compute the field itself and codes to illustrate
applications including a modified version of a public serial initial conditions
generator. We document the software and present the results of a few basic
tests of the field. The properties and method of construction of Panphasia are
described in full in a companion paper Jenkins 2013.
