Linear correlation coefficients between models s20rts and bdp00

• left plot: total correlation for l_max=20 (solid,magenta line) and l_max=8 (dashed, pink line) as a function of depth z
• middle plot: correlation r as a function of depth z and spherical harmonic degree l
• right plot: model RMS on a logarithmic scale

• model s20rts: view normalized power per degree, power per degree, radial correlation, or
