  A global fit to the data from different collaborations (CELLO, CLEO, BaBar)
on the pion-photon transition form factor is carried out using light-cone sum
rules. The analysis includes the next-to-leading QCD radiative corrections and
the twist-four contributions, while the main next-to-next-to-leading term and
the twist-six contribution are taken into account in the form of theoretical
uncertainties. We use the information extracted from the data to investigate
the pivotal characteristics of the pion distribution amplitude. This is done by
dividing the data into two sets: one containing all data up to 9 GeV$^2$,
whereas the other incorporates also the high-$Q^2$ tail of the BaBar data. We
find that it is not possible to accommodate into the fit these BaBar data
points with the same accuracy and conclude that it is difficult to explain
these data in the standard scheme of OCD.
