abstract = "This work examines the large-scale aspects of magnetic field
reconnection at the Earth's dayside magnetopause. We use two sets
of reconnection events, which are identified mostly by the in situ
detection of accelerated and Alfv{\'e}nic plasma flows. We
intercompare three analytical models that predict the reconnection
X line location and orientation, namely, the Trattner et al.
(2007) and Swisdak and Drake (2007) models and also a modified
version of the component merging model. In the first set of
reconnection observations, we show three fortuitous,
quasi-simultaneous dayside magnetopause crossing events where two
widely separated spacecraft detect reconnection signatures, and
the X line location and orientation can be inferred from the
observations. We compare X line model predictions to those
inferred from observations. These three reconnection events
indicate the presence of an extended (>7 Earth radii in length),
component-type reconnection X line on Earth's dayside magnetopause
connecting and structuring the reconnection signatures at
locations far apart. In the second set of reconnection events, we
analyze the X line models' performance in predicting the observed
reconnection outflow direction, i.e., its north-south and/or
east-west senses, in a total of 75 single, rather than multiple
and quasi-simultaneous, magnetopause crossing events, where
reconnection-associated plasma flows were clearly present. We
found that the Swisdak and Drake's (2007) X line model performs
slightly better, albeit not statistically significant, when
predicting both accelerated plasma flow north-south and east-west
components in 73% and 53% of the cases, respectively, as compared
to the Trattner et al. (2007) model (70% north-south and 42%
east-west) and the modified component merging model (66%
north-south and 50% east-west).",
