Since I had no one able to check my Spherical Trigonometry data it was necessary for me to continue to check my own data in search of errors - not an easy task.

These resulting corrections have no affect on the book except for the pages listing the vortex coordinates. So if you are not planning on doing further research using that data these corrections would be of no interest to you.

But, if you are planning to do further research on the vortex locations, then click on this ZIP FILE link to download a zip file with the corrected pages in book format.

As a bonus for those planning on further research I have included the complete Spherical Trigonometry formulas in EXCEL format.

Enjoy
