Detailed Description

fundamental data structure for SplineInterpolatedPeaks

In many cases, data points in MS spectra (or chromatograms) are not equidistant in m/z (or RT) but consist of packages of data points separated by wide m/z (or RT) ranges with zero intensity. SplinePackage contains the spline fit of a single set of such data points.
