Correction to “Separator reconnection at Earth's dayside magnetopause under generic northward interplanetary magnetic field conditions”

[1] In the paper “Separator reconnection at Earth's dayside magnetopause under generic northward interplanetary magnetic field conditions” by John C. Dorelli, A. Bhattacharjee, and J. Raeder (Journal of Geophysical Research, 112, A02202, doi:10.1029/2006JA011877, 2007), there were several errors. The fifth sentence of the abstract should read as follows: [2] Using a technique described by Greene (1992) to track the magnetic nulls in the system, we identify the dayside X line as a magnetic separator line, a segment of a magnetic field line which extends across the dayside magnetopause, terminating in the cusps. [3] The caption for Figure 10 is also incorrect and is given correctly here. Figure 10. This figure illustrates the geometry of component reconnection, viewed from the Sun. Red arrows labeled “Bi” show the magnetospheric magnetic field; blue arrows labeled “Bo” show the magnetosheath magnetic field. The left figure shows a case where reconnection is geometrically possible, according to the Sonnerup criterion. The right figure shows a case where reconnection is precluded by the Sonnerup constraint (i.e., the projection of the magnetic field in the plane perpendicular to the average current in the sheet has no hyberbolic null). [4] Finally, there was a missing acknowledgment. The correct Acknowledgments section appears here. [5] This research was made possible by the following grants: NASA NNG05GE87G and NNG05G158G; NSF ATM-0503268, ATM-0543202, ATM-0422764, ATM-0420905, and ATM-0503189; and DOE DE-FG02-05ER54832. Global MHD computations were carried out on the Zaphod Beowulf cluster at the UNH Institute for the Study of Earth, Oceans and Space.
