[static] std::tuple<double, double, double, double> Generic::weightedCenterOfMass(const pappso::Trace &input_trace)

Calculates the weighted center of mass or the curve input_trace.

The returned tuple has four members:

• Member 0: center of mass, the abscissa of the center of mass of the input curve;
• Member 1: y max, the intensity at the center of mass
• Member 2: sigma [related to the FWHM according to: FWHM = 2 * sqrt(2 * std::log(2)) * sigma]
• Member 3: b, the baseline correction (0, at the moment)

If input_trace is empty, the returned tuples has all its members set to 0.0.
