The algorithm creates a new 1D workspace containing all maxima as well as their X boundaries and error. This is used in particular for single crystal as a quick way to find strong peaks.
# Create a workspace with two peaks in each spectrum
ws = CreateSampleWorkspace(Function='Multiple Peaks')
# Find the max values
max_ws = Max(ws)
# Check the returned values
print 'Maximum found at bin [',max_ws.readX(0)[0],',',max_ws.readX(0)[1],'], value',max_ws.readY(0)[0]
print 'In original workspace'
print 'Bounds of bin 30 [',ws.readX(0)[30],',',ws.readX(0)[31],'], value',ws.readY(0)[30]
# Find another peak
max_ws = Max(ws,RangeLower = 7000)
# Check the returned values
print 'Maximum found at bin [',max_ws.readX(0)[0],',',max_ws.readX(0)[1],'], value',max_ws.readY(0)[0]
print 'In original workspace'
print 'Bounds of bin 60 [',ws.readX(0)[60],',',ws.readX(0)[61],'], value',ws.readY(0)[60]
Maximum found at bin [ 6000.0 , 6200.0 ], value 10.3
In original workspace
Bounds of bin 30 [ 6000.0 , 6200.0 ], value 10.3
Maximum found at bin [ 12000.0 , 12200.0 ], value 8.3
In original workspace
Bounds of bin 60 [ 12000.0 , 12200.0 ], value 8.3
