If we decide later on to send our beam line to another destination, they should be able to quickly give us the density profile for that beam line as they have had their programs completed. I will get more information from them on the uncertainties of these matter densities as we will need this information to estimate the error bars. Data below is in the format of (lat, long, ellipsoid height, density): lat and long are both given in degrees. For lat, "+" refers to N. For long, "-" refers to "W". The ellipsoid heights are given in meters. All the coordinates were calculated with reference to NAD83 (semi-major axis: a = 6378137.000m; the reciprocal flattening: 1/f = 298.2572221008827). The matter densities are in kg/(m^3).

The estimated densities are subject to large uncertainties and these uncertainties are diffcult to estimate. They can be especially large in near the crust-mantle transition (depths about 30-40 km). In future, if you will need, I can send you densities for any profile. Now it is just a matter of quikly running already exsiting programs.
