******* ***************
** User callable
** Takes background subtracted D7 data of 1, 2 or 6 phases and corrects for
** multiple scattering using the isotropic approximation of Wells and Cywinski,
** and the secondary scattering coefficients of Blech and Averbach. At present,
** deals only with cylindrical samples. Correction of TOF data not yet implemented.
