<p>Hi David,<br>

</p>

<p><br>

</p>

<p>Thanks for alerting this to us. These numbers came from Ed Doddridge's SO setup, and values probably overlooked as the tutorial lat-lon domain evolved to final form...<br>

</p>

<p>but not sure why they were originally chosen as such. Perhaps Ed can recall?<br>
