Parameters: |
- fm Focal mechanism that is either number of mechanisms (NM) by 3
(strike, dip, and rake) or NM x 6 (M11, M22, M33, M12, M13, M23 - the
six independent components of the moment tensor, where the coordinate
system is 1,2,3 = Up,South,East which equals r,theta,phi). The strike
is of the first plane, clockwise relative to north.
The dip is of the first plane, defined clockwise and perpendicular to
strike, relative to horizontal such that 0 is horizontal and 90 is
vertical. The rake is of the first focal plane solution. 90 moves the
hanging wall up-dip (thrust), 0 moves it in the strike direction
(left-lateral), -90 moves it down-dip (normal), and 180 moves it
opposite to strike (right-lateral).
- facecolor Color to use for quadrants of tension; can be a string,
e.g. 'r', 'b' or three component color vector, [R G B].
Defaults to 'b' (blue).
- bgcolor The background color. Defaults to 'w' (white).
- edgecolor Color of the edges. Defaults to 'k' (black).
- alpha The alpha level of the beach ball. Defaults to 1.0
(opaque).
- xy Origin position of the beach ball as tuple. Defaults to
(0, 0).
- width (int) Symbol size of beach ball. Defaults to 200.
- size Controls the number of interpolation points for the
curves. Minimum is automatically set to 100.
- nofill Do not fill the beach ball, but only plot the planes.
- zorder Set zorder. Artists with lower zorder values are drawn
first.
- mopad_basis The basis system. Defaults to 'USE'. See the
Supported Basis Systems section below for a full list of supported
systems.
