Defines a sequence of values that are tangentially spaced.
de = s * tan( u ) + de0
where: u = uniformly spaced sequence s = spreading factor de = resulting sequence of angles
This spacing organizes the D/E angles of acoustic rays such that they intersect horizontal planes with an even spacing in an isovelocity environment.

Construct sequence of tangentially spaced angles using first value, last value, size, and center.
first | Angle at start of sequence (deg). | |
last | Angle at end of sequence (deg). | |
size | Number of elements in this sequence. | |
center | Angle at which rays are densest (deg). | |
spread | Spreading factor. |
