Molecular Data:

1. Molecular coherent form factors for all sixteen materials
   1. A reduced data set, interpolated at the same x values that Hubbell used in his set of relativistic atomic coherent form factors. Range of x is 0 to 10^10 per nm with 100 data points. Values in this table above x=10 per nm are atomic form factors from Hubbell & Øverbø. This is the data set that will appear in the publication.
      Also available with x in units of "per Angstrom"
   2. A full data set from the measured scattering distributions. Range of x is 0 to 13 per nm with 586 data points.
      Also available with x in units of "per Angstrom"
   3. Legend for the data sets above.

2. More detailed files are also available for each material separately. These files contain four columns: x values (per nm), form factor using atomic form factors, measured molecular form factor and the uncertainty of the measured molecular form factor.
