Figure 8
Discrepancy values between $[{\rho _{\rm FT}}]$ and $[{\rho _{\rm VRM}}]$ for the crambin model (PDB code: 1crn). (a) Relative error $[{e_{\rm rel,max}}]$ between $[{\rho _{\rm FT}}]$ and $[{\rho _{\rm VRM}}]$ maps inside the molecular mask for the protein model, shown as a function of the image $[{r_{\rm max}}]$ ; the maps are calculated for different map resolution $[{d_{\rm min}}]$ with $[{q_{\rm add}} = 0.5]$ ; the B values are assigned according to main values from Fig. 7

. (b) The same as (a) but with all B = 5 Å².
