Fix Dip Angle

Description

Fix az, dip angles so they fall in correct quadrant.

Usage

FixDip(A)

Arguments

List:

`A`	az azimuthm angle, degrees dip dip angle, degrees

Details

Quadrants are determined by the sine and cosine of the dip angle: co = cos(dip) si = sin(dip) quad[co>=0 & si>=0] = 1 quad[co<0 & si>=0] = 2 quad[co<0 & si<0] = 3 quad[co>=0 & si<0] = 4

Value

List:

`az`	azimuthm angle, degrees
`dip`	dip angle, degrees
