is invoked from the main level of XPLOR.
 <dynamicspowerstatement> :==

 <trajectorystatement>
 defines the input data; see Section
11.1.3.
 BACK=<logical>
 performs Fourier
backtransformation on power spectrum to
obtain the vector autocorrelation function (default: FALSE).
 CLENgth=<realps>
 provides length of correlation
function in units of psec;
it affects only the
output file (default: 10).
 COUTput=<filename>
 writes the correlation function
to the specified file.
 PLENgth=<real>
 provides the length of the
power spectrum in units of psec; it affects
only the output file, not the calculation (default: 1000).
 POUTput=<filename>
 puts the power spectrum into the
specified file.
 POWER2=<integer>
 is an optional specification of a power
of 2 for the FFT (default: 1).
 PSKIp=<int>
 is the skip value for
the printout of the power spectrum. It does not
affect the calculation. If pskip is zero, no power spectrum is written
(default: 1).
 TRIM=<logical>

trims the first (largest) peak
from the power spectrum if TRIM is TRUE; if a
correlation function is calculated later
and the peak was at 0, this is equivalent to shifting the long time limit
of the correlation function to 0 () (default: FALSE).
 WINDow=( <real> <real> )

sets to zero everything in the power spectrum that is
outside the window defined by the two values in units of
psec (default: (0,1000)).
