 The ``results`` directory will contain all relevant outputs of the current **prefactor** run, once the pipeline has finished:
-    - fully calibrated data sets
+    - fully calibrated datasets, concatenated with ``num_SBs_per_group`` subbands per MS file and averaged, if desired (see averaging options below). The DATA column of each MS contains the calibrated data (with the direction-independent solutions applied).
     - logfiles in ``results/logs``
     - summary file (JSON format) in ``results/summary``
     - calibration solutions in ``results/cal_values/cal_solutions.h5``
