XML interfate to binning schemes, for use with the unfolding algorithm TUnfoldDensity.

Binning schemes are used to map analysis bins on a single histogram axis and back. The analysis bins may include unconnected bins (e.g nuisances for background normalisation) or various multidimensional histograms (signal bins, differential background normalisation bins, etc).

If you use this software, please consider the following citation

S.Schmitt, JINST 7 (2012) T10003 [arXiv:1205.6201]

Detailed documentation and updates are available on http://www.desy.de/~sschmitt

Please consult the documentation of the class TUnfoldBinning about how to use binning schemes. This class provides methods to read and write binning schemes in the XML language. There is also a method which writes out a dtd file for validation.

Example XML code

The example below encodes two binning schemes, detector and generator. The detector scheme consists of a single, three-dimensional distribution (pt,eta,discriminator). The generator scheme consists of two two-dimensional distributions, signal and background.
