One reference to Appendix C should actually reference Appendix D

[taylor13]

After Example 4.3 the following sentence appears:

"In this example the standard_name value atmosphere_sigma_coordinate identifies the following definition from Appendix C, Standard Name Modifiers which specifies how to compute pressure at gridpoint (n,k,j,i) where j and i are horizontal indices, k is a vertical index, and n is a time index:"

This should refer to Appendix D, Dimensionless Vertical Coordinates, not Appendix C.

Defect is fixed.
