Fo,Fo+delta (the green line) |
the expected correlation between the observed structure factor amplitudes (__Fo(h)__) and the amplitudes plus the experimental noise (__Fo(h)__+sigma(h)*Gauss(0,1)). |

Fo,Ffrg (the white line) |
the correlation coefficient between the observed structure factor amplitude (__Fo(h)__) and the amplitude of the structure factor as calculated from the partial structure in the fragment file (__Ffrag(h)__) without bulk solvent correction |

Fo,Fc (the yellow line) |
the correlation coefficient between observed structure factor amplitude (__Fo(h)__) and the amplitude of the total structure factor as calculated from the current model (__Fc(h)__), with bulk solvent correction |

Fc,Fxpct (the blue line) |
the correlation coefficient between the amplitude of the total structure factor as calculated from the current model (__Fc(h)__) and the expectation value for the same amplitude as calculated from the Rice distribution (__Fxpct(h)__). These correlation coefficients depart from one because of the error model associated with the partial structure and the missing atoms. |
