Power spectrum (black dots) calculated for the velocity centroid (top) and the thick slice emission (bottom) over the velocity range −10.2 < v_LSR < 11.7 km s^-1. For the velocity centroid a power law with γ = −2.78 ± 0.03 was fit and respectively γ = −3.28 ± 0.04 for the average emission (black lines), in both cases for k< 0.07 arcmin^-1 (vertical line). In addition the power spectra for 148° < Φ < 163° (red) and 58° < Φ < 73° (green) are plotted. The average anisotropy factor for 0.007 < k < 0.07 arcmin^-1 is Q_aver = 3.2 for the centroid and Q_aver = 2.6 for the average emission.
