Plot Ternary Point

Description

Add a point to a ternary plot

Usage

ternfoc.point(deltaB, deltaP, deltaT)

Arguments

`deltaB`	angle, degrees
`deltaP`	angle, degrees
`deltaT`	angle, degrees

Details

Plot point on a Ternary diagram using Froelich's algorithm.

Value

List

`h`	vector of x coordinates
`v`	vector of y coordinates

Note

Use Bfocvec(az1, dip1, az2, dip2) to get the deltaB angle.

Examples

Msdr = CONVERTSDR(55.01, 165.65,  29.2   )
 MEC = MRake(Msdr$M)
  MEC$UP = FALSE
   az1 = Msdr$M$az1
  dip1 = Msdr$M$d1
  az2 = Msdr$M$az2
  dip2 = Msdr$M$d2
  BBB = Bfocvec(az1, dip1,  az2,  dip2)
  V = ternfoc.point(BBB$Bdip, Msdr$M$pd, Msdr$M$td )
