Provide a clear and concise overview of the new feature requested.

We update the aerosol table values for mineral dust in FJX_scat-aer.dat in Extdata directory. The description about fitted log-normal distribution is given in the table itself (geometric radius and standard deviation). The updated values are calculated are based on the spheroidal shape for the dust particles. Please replace the current existing file with the file attached to this request.
The single scattering properties at 200nm are calculated using the refractive index for 300nm as there is no refractive index value available for 200nm.
Please find the attached file. The attached file is in .txt format. It should be converted to .dat format before implementation so that we don't have to make changes in the source code.
