[PyMOL] Angstrom-squared values for solvent/protein contact surface per residue

[Melanie Rogers]

Dear Pymol Users, 

Is it possible to extract numerical values, (i.e. Angstrom-squared per
residue)
for the solvent/protein contact surface for individual residues in a crystal
structure using Pymol?  

Thank you,
