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
