The table for the space-like doubly-virtual pion transition form factor F(q_1^2,q_2^2) is organized as follows:

1st column: Q_1^2 [GeV^2]
2nd column: Q_2^2 [GeV^2]
3rd column: central value for F(-Q_1^2,-Q_2^2) [GeV^{-1}]
4th column: uncertainty from F_{\pi\gamma\gamma} [GeV^{-1}]
5th column: dispersive uncertainty [GeV^{-1}]
6th column: BL uncertainty, upwards [GeV^{-1}] 
7th column: BL uncertainty, downwards [GeV^{-1}] 
8th column: asymptotic uncertainty [GeV^{-1}]
9th column: total uncertainty, upwards [GeV^{-1}]
10th column: total uncertainty, downwards [GeV^{-1}]

The total uncertainty is calculated as the quadrature sum of the individual sources.
To reduce the size of the data file, we have used the symmetry F(q_1^2,q_2^2)=F(q_2^2,q_1^2), 
from which the results for the missing combinations of {Q_1^2,Q_2^2} can be reconstructed.

Note that, while the central values for F(-Q_1^2,-Q_2^2) reproduce exactly the central value
for a_\mu^{\pi^0-pole} as given in the paper, the uncertainty does not follow from the quoted total uncertainties alone.
Since the form factor enters squared, the individual sources of uncertainty need to be considered separately, which,
based on the breakdown provided in the data file, then reproduces approximately our quoted error 
for a_\mu^{\pi^0-pole}.
