Equations (15) and (19)
express the partial derivatives
of the offset wavenumbers in the rotated coordinates.
We need to evaluate the partial derivatives
of the offset wavenumbers in the data coordinates.
Therefore, we need to differentiate the expressions
defining the inverse rotation; that is, differentiate
with respect to the following expressions:
| |
(19) |

| (20) |

The partial derivatives are then given by the following expressions:

| |
(21) |

| (22) |
