Pulsar timing residuals due to individual non-evolving gravitational
  wave sources
  The pulsar timing residuals induced by gravitational waves from non-evolving
single binary sources are affected by many parameters related to the relative
positions of the pulsar and the gravitational wave sources. We will fully
analyze the effects due to different parameters one by one. The standard
deviations of the timing residuals will be calculated with a variable parameter
fixing a set of other parameters. The orbits of the binary sources will be
generally assumed to be elliptical. The influences of different eccentricities
on the pulsar timing residuals will also studied in detail. We find that
effects of the related parameters are quite different, and some of them present
certain regularities.
