Final physical properties of the WASP-44 system. The first error bar for each parameter is the statistical error, which stems from the measured spectroscopic and photometric parameters. The second error bar is the systematic error arising from the use of theoretical stellar models, and is given only for those parameters which have a dependence on stellar theory. The results from Anderson et al. (2012) are included for comparison.
