[BioC] gcrma package

I would like to understand where do affinity.spline.coefs used in function 
compute.affinities come from ?

library(gcrma)
data(affinity.spline.coefs)

affinity.spline.coefs
X1 X2 X3 X4 X5 X1
-0.55004171 -0.58579091 -0.08870557 -0.47774242 0.23205570 0.58002746
X2 X3 X4 X5 X1 X2
0.61274425 0.10294309 0.57388808 -0.28334367 0.01350914 -0.02030805
X3 X4 X5
-0.14747469 0.05436463 -0.10124882

I read the reference
Hekstra, D., Taussig, A. R., Magnasco, M., and Naef, F. (2003)
Absolute mRNA concentrations from sequence-specific calibration of
oligonucleotide array. Nucleic Acids Research, 31. 1962-1968,
but don't find any answer to my question.


Thank you in advance!
