The scales on the images of the current density in the original version of the paper were missing a factor of c. The estimated value for the effective diffusivity needs to be corrected by a factor of 4π and should be replaced by ηeff = 1.6 × 1011 cm2 s−1. Finally, the units on the y-axis of Fig. 16 should have been DN pix−1 s−1 instead of DN pix s. The new versions of the figures presented here have been corrected. These corrections do not affect the conclusions of the original paper.

Fig. 10. Cut through the loop at the apex (cross section perpendicular to the loop axis). (a) Temperature; (b) electron density; (c) magnitude of the velocity perpendicular to the loop axis; (d) emission in the 211 Å channel of AIA; (e) axial component of the velocity; (f) axial component of the Poynting flux; (g) axial component of the current density; and (h) emission as seen with the Al-poly filter of XRT. The black arrows illustrate the horizontal velocity field. The yellow box highlights the location of a vortex with enhanced temperature and density. The snapshot was taken at t = 41.02 min. |

Fig. 13. Cut through the loop at the apex (cross section perpendicular to the loop axis). (a) Temperature; (b) sum of viscous and resistive heating; (c) squared current density; and (d) 2D histogram of the total numerical heating rate vs. the squared current density. |

Fig. 14. 2D histograms of the temperature, total heating, squared current density, and X-ray emission at the apex vs. the velocity perpendicular to the loop axis. The X-ray emission has been computed to correspond to what XRT on Hinode would measure. The quantities have been averaged over a time range of 15 minutes. |
