• Smoothing methods

  • boxcar - Smoothing by convolving the spectrum with a boxcar window with a user-specified width.
  • smoothingspline - Smoothing using the error spectrum to create a smoothing spline fit to spectrum.
  • gaussian - Smoothing by convolving the spectrum with a Gaussian window with a user-specified FWHM.
  • lowpass - Smoothing using a low-pass filter as described in Marion et al. (2009).

• Error estimate methods

  • rawsmooth - Estimate the error spectrum by smoothing the |raw-smooth| residuals.

• Feature and measuring methods

  • velocity.minima - Measure velocities by identifying minima in the smoothed spectrum.
  • velocity.gaussians - Measure velocities by fitting Gaussians to sections of the spectrum.
  • width.pew - Measure pEW by connecting maxima in the smoothed spectrum.
  • width.shallowpew - Define pEWs by fitting the continuum on each side of the feature.
  • width.gaussians - Measure widths by fitting Gaussians to sections of the spectrum.

• Uncertainty estimate methods

  • propagation - Get errors from propagation of uncertainty.
  • montecarlo - Remeasure features in N realizations of the spectrum.
