imageSH

P-wave radiation pattern

Amplitude of SH-wave radiation pattern from Double-Couple earthquake

imageSH(phiS, del, lam, SCALE = FALSE, UP = FALSE, col = NULL)

`phiS`	strike
`del`	dip
`lam`	lambda
`SCALE`	logical, TRUE=add scale on side of plot
`UP`	upper/lower hemisphere
`col`	color

This program calls radP to calculate the radiation pattern and it plots the result using the standard image function
