In HEN_HOUSE/pegs4/density_corrections/compounds/rw-1watersubstitute_polyethenebased.density the density of the material is 9.6999998. Should it be 0.96999998?

Most probably, of course!! Can anybody provide a reference on this particular material? It would be nice to confirm the numerical value as well.

We have to check the actual density correction values of course, not just the density value in the header.

I went through the density correction files trying to find one suitable for RMI SW and came across this one. Unfortunately I don't have further experience using it or information about it, but after some Google search, in http://iopscience.iop.org/0031-9155/60/24/9403 and in the reference therein there is some supporting information.

The density effect correction values in the rw-1watersubstitute_polyethenebased.density themselves do correspond to the (wrong) density of 9.6999998 instead of 0.96999998. I am preparing a new file with the correct data.

Fix #347: wrong density for rw-1 material
713f98f 
Regenerate the density effect correction file for the RW-1 water
substitute material, for the correct density ~0.97, instead of the
previously erroneous value of ~9.7. The updated data was obtained from
the estar program, using the correct density, but otherwise unchanged
I-value and chemical composition values, as shown in the file header.
