ScanContours

This action performs a contour scan over a 2D space, employing the Minuit contour method.

Usage:

+ScanContours.cont2D{
  +test{
    <datasetName="modelData">
    <x="frac",y="sigma_g2">
    <n=100>
  }
}

As this performs a series of fits, it can take quite long to run. Since the contour method is iterative and cannot easily be parallelized, the parallelizable scan of the full parameter space using WriteScanLikelihood is usually more efficient.
