[Clascomment] OPT-IN: Measurement of Single and Double Spin Asymmetries in Deep Inelastic Pion Electroproduction with Longitudinally Polarized Target

[Enzo DeSanctis]

I like the paper and have only the minor comments below:

1/r/2/6: I wouldn’t call “measurements” the calculations on lattice.
2/l/2/14: we state that charged pions were identified using TOF. Why didn’t we use the tracking detectors?
2/l/4/..: What about the acceptance effects on the systematic uncertainties?
2/r/Fig.1: I would use larger size character for the legend.
2/r/3/1-3: I would explicitly recall here HERMES and CLAS writing: ‘The double spin asymmetries measured by HERMES and CLAS at different beam energies (by a factor of ~5) and different values of Q^2 …’.
2/r/3/5-6: drop ‘(see Fig.2)’, it is an unnecessary repetition.
3/l/1/4: here we quote a width of 0.7, while in caption of Fig. 2 we quote 0.68.
3/l/Fig.2: in the x-axis the figures 1 of the first and second plots overlap with the figures 0 of the second and third plots.
3/r/Fig.3: I would use larger size for the pi^+, pi^0 and pi^- in the legend.
3/r/1/7: from the caption of Fig.3 it results that also the integrated sin2phi contribution for pi^- is compatible with zero. Why do we comment on the pi^0 only?
