pcac: Computes the pcac mass

In hadron: Analysis Framework for Monte Carlo Simulation Data in Physics

Computes the pcac mass

Description

Computes the pcac mass from the PP and the AP (PA) correlators and estimates the errors using the gamma method

Usage

pcac(psfilename, apfilename, pafilename, from = 3, to = 3, fit = F,
  skip = 0, plotit = F, S = 1.5)

Arguments

psfilename	filename of the file from which to read the PP correlator. It is supposed to be in GWC code format. mandatory.
apfilename	filename of the file from which to read the AP correlator. It is supposed to be in GWC code format. Either PA or AP correlator (or both) must be given. If both are given, both are used by averaging.
pafilename	filename of the file from which to read the PA correlator. It is supposed to be in GWC code format. Either PA or AP correlator (or both) must be given. If both are given, both are used by averaging.
from	the effective mass is computed starting with t=from
to	the effective mass is computed ending with t=to
fit	logical. if TRUE a fit is performed to all t-values to determine the pcac mass.
skip	no of measurements to skip at the beginning of the file
plotit	logical. if TRUE a plot is drawn.
S	passed to uwerr, see documentation of uwerr.

Details

the symmetric difference operator is used.

Value

returns a data.frame with the results. The object is also of class massfit which can be plotted using the generic function plot.
