Baseline Correction for Shear Stress/Strain Time Histories?

In the Time Series Output Specification tab, shear stress and shear strain time histories have an option for baseline correction. The manual seems to indicate that baseline corrections are only made for displacement, velocity and acceleration time histories. Does checking the “Baseline Correct” box for a shear stress or shear strain time history have any effect on the output stress/strain time history?

Thanks very much

    For the shear stress and shear strain time series, the baseline correction is only removal of the mean from the time series. For the acceleration/velocity/displacement time series, the baseline correction is done by fitting a fourth order polynomial to the displacement time series and applying the correction to the acceleration time series.
