To create a postscript plot, called plot.ps, of the net and background counts, from the source and background spectra, spectrum.ds and background.ds, where the channel energy is geometrically rebinned with a modulus of 2.0 before being plotted on the x-axis, a command such as,
especplot srcspectrumset="spectrum.ds" bkgspectrumset="background.ds" withbinning=yes binsize=-2.0 plotdevice="/VPS" plotfile="plot.ps"
can be used.
