Statistics are given (in resolution shells) for the isomorphous and the anomalous signal.
Important: to more clearly identify outliers in [[XSCALE]]d data, you may want use the -w option. This can be helpful since the ''a'' and ''b'' parameters of the error model are adjusted by XSCALE such that the sigmas are very high, which reduces the delta-CC<sub>1/2</sub> signal.
A complete description of how to process serial crystallography data with XDS/XSCALE is given in [[SSX]]. A program that implements the method of [https://doi.org/10.1107/S1399004713025431 Brehm and Diederichs (2014)] and theory of [https://doi.org/10.1107/S2059798317000699 Diederichs (2017)] is [[xscale_isocluster]].
