[ccp4bb] Rice vs Sim vs ACNSFD

2009-04-09 Thread Bernhard Rupp
Dear All, I am unsure about the likelihood function nomenclature. I have seen the Sim function called the Rice function, and aIso have read the acentric conditional normalized structure factor distribution (ACNSFD) called the Rice function (the centric conditional normalized structure
