xcor1 - subroutine to perform one sided autocorrelation
call xcor1(npts,s1,p,fsamin,mpts,tmingt,tmaxgt)
Basic Seismic
Utilities (BSU) subroutine which performs a one-sided
autocorrelation on signal s1. The output is signal, p. The
boxcar window is specified by tmingt and tmaxgt. The number
of lags is specified by mpts.
Fortran Version.

mpts (int)
Number of lags to compute autocorrelation.
