IC1 is a data frame with 10000 cases (rows) and 6 variables
(columns) named thickness, biref, R, G, B and retardation.
Details
Low-resolution data that would be obtained by running the
InterferenceTable function with
thickVect = seq(0.01,50,length.out = 50) micrometers and
birefVect = seq(2e-4,1e-2,by = 5e-4)
