Note:
For table1a, PRADK =1.1194E+01, Abundance scale = 0.31620
For table2a, PRADK =1.1434E+01, Abundance scale = 0.32500
For table3a, PRADK =1.1200E+01, Abundance scale = 0.32500
For table4a, PRADK =1.1198E+01, Abundance scale = 0.3250
For table5a, PRADK =1.1437E+01, Abundance scale = 0.32500
where PRADK is the radiation pressure at the surface
For each table: Vturb = 2.0 km/s
