A modern re-examination of the geophysical data was able to take account of factors the 1774 team could not. With the benefit of a 120-km radius digital elevation model, greatly improved knowledge of the geology of Schiehallion, and the help of a computer, a 2007 report produced a mean Earth density of 5,480 ± 250 kg·m. When compared to the modern figure of 5,515 kg·m, it stood as a testament to the accuracy of Maskelyne's astronomical observations.
