Small Circle on Stereonet

Description

Calculate and plot small circle on Stereo net at arbitrary azimuth, orientation and conical angle

Usage

addsmallcirc(az, iang, alphadeg, BALL.radius = 1, N = 100, add = TRUE, ...)

Arguments

az	Azimuth of axis
iang	angle of dip, degrees
alphadeg	width of cone in degrees
BALL.radius	size of sphere
N	NUmber of points to calculate
add	logical, TRUE=add to existing plot
...	graphical parameters

Details

Given the azimuth and dip of a vector, plot the small circle around the pole with conical angle alphadeg

Value

LIST:

x	x-coordinates
y	y-coordinates

Note

alphadeg is the radius of the conic projection
