(a) The resolution based on the Fourier shell correlation between the average map and the ground truth map, using the ½-bit threshold. (b) The resolution based on the PRTF, using the e−1 threshold. For both measures, the resolution gets worse with increasing background. Note the sudden improvement in RPRTF with increasing background for the weaker-signal cases. These correspond to poor reconstructions in (a), with high RFSC, illustrating a situation where the PRTF suggests an exaggerated resolution.
