The data set consists of section profile parameters (assumed to come from prolate spheroids) of fitted ellipses based on measured section particles of an aluminium matrix composite [5] from metallographic analysis. The data set can be used to reconstruct the trivariate spatial (prolate) spheroid distribution.
data(data15p)
A matrix of columns named A (major semi-axis length), C (minor semi-axis length),
S=C/A (shape factor), alpha (polar angle in the intersecting plane) and coordinates (x,y)
of the centers of fitted ellipses.
