The usual (like in MOSFLM and other programs) correction based on resolution shell and frame number is performed in [[XDS]] as part of the CORRECT step - it can be switched off by omitting DECAY from the default CORRECTIONS= DECAY MODULATION ABSORP). This correction is also available from XSCALE.

DECAY correction is also the default in XSCALE.  


It is instructive to inspect DECAY.pck (using "VIEW DECAY.pck"). This visualizes the scale factors employed by the CORRECT step (the equivalent files from XSCALE are called DECAY_*.pck); the right sidebar gives the mapping between colours and numbers. Along the horizontal axis the frame number is shown, along the vertical axis the resolution shell.
