+**Example - Removing exponential decay from a MUSR run:**
+
+.. testcode:: ExMUSR
+
+   # Load first period of a MUSR run
+   input = LoadMuonNexus('MUSR0015189.nxs', EntryNumber=1)
+
+   # Remove uninteresting bins
+   input = CropWorkspace('input', XMin=0.55, XMax=12)

+   # Remove exp. decay
+   output = RemoveExpDecay('input')

+   # Bins to compare

+
+   # Get values before&after and format them as strings for output
