Item Description
The real space correlation coefficient for the instance. This is an alternative to RSR for assessing how well
the residue's calculated electron density map matches the EDS electron density map calculated from the
experimental diffraction data. A value above 0.95 normally indicates a very
good fit. RSCC around 0.90 are generally OK. A poor fit results in a value around or below 0.80.
X-ray specific produced by the EDS step.
