We use the results for the structure function FL for a gluon target with a nonzero transverse momentum squared at the order α s, obtained in our previous paper, for comparison with recent H1 experimental data for FL at fixed W values and with collinear GRV predictions in the leading-order and next-to-leading-order approximations.
