I have some question about interpreting PDG particle cross section data sets' metadata fields. The data sets I'm having questions for are http://pdg.lbl.gov/2011/hadronic-xsections/hadron.html
For example, the data set for p-bar p collision http://pdg.lbl.gov/2011/hadronic-xsections/pbarp_total.dat
The data set has meta data fields as shown at the top of the .dat file. I have questions about the following metadata fields. Apologies if the questions are silly.
Is this the energy of the beam particle w.r.t. lab coordinates?
Again, w.r.t. lab coordinates?
Not exactly sure what this is, but most files has 0 for this value, what's it?
Is this multiplicity from phase space configuration? Could you given a reference or an example so I may check details of the derivation?
Momentum of the beam particle w.r.t. lab reference coordinate?
Minimum and maximum of PLAB? So a data point in the plot will have an x coordinate with uncertainty? how should it be plotted then? It seems in the plot in the PDF the x-coordinate doesn't have "bars" but only the y-coordinate has it. How is the uncertainty of x taken into account?
What's this? is it visible in the plot at all?
For example, "ELIOFF 62 PR 128, 869", but what is the last number here? My guess is .
