ideally, the error should be less than half the minimum spot separation. If the error is larger than that, you'll have to inspect the table in IDXREF.LP which investigates alternative origin positions. XDS does optimize the beam position (or rather the beam direction, but that determines the beam position). | ideally, the error should be less than half the minimum spot separation. If the error is larger than that, you'll have to inspect the table in IDXREF.LP which investigates alternative origin positions (the one that has the heading "***** SELECTION OF THE INDEX ORIGIN OF THE REFLECTIONS *****"). XDS does optimize the beam position (or rather the beam direction, but that determines the beam position). See [[Finding out ORGX ORGY]] for a program that estimates ORGX, ORGY from ice rings. | ||
