Double meson production observables    (Solution BG2010-01)

The observables can be calculated from phase scpace MC events weighted by the differential cross sections (NN, YN,...) for beam and/or target polarization experiment. The events are given as:

Photoproduction data:
1st line: NN YN CN NX NZ YX YY YZ CX CZ
2nd line: Px Py Px E for 1st particle
3rd line: Px Py Px E for 2nd particle
4th line: Px Py Px E for 3rd particle
Pion-induced data:
1st line: NN NX NZ
2nd line: Px Py Px E for 1st particle
3rd line: Px Py Px E for 2nd particle
4th line: Px Py Px E for 3rd particle

Here N stands for nonpolarized case, Y,X,Z -linear polarization along corresponding axis, C - circular polarization.
The first leter stands for the beam polarization and second one for the target polarization.
