> SM : SIDC classical method : based on an interpolation of Waldmeier's
> standard curves; the estimated error ranges from 7% (first month) to
> 35% (last month)
> CM : Combined method : the combined method is a regression technique
> coupling a dynamo-based estimator with Waldmeier's idea of standard
> curves, due to K. Denkmayr.
