| InputWorkspace | Input | MatrixWorkspace | Mandatory | The name of the input 2D workspace. |

| Spectra | Input | int list | The workspace indices to remove the exponential decay from. |
This algorithm removes the exponential time decay from the specified muon spectra, leaving the rest unchanged. By default, all the spectra in a workspace will be corrected.
The formula for removing the exponential decay is given by:
where 
is the muon lifetime (2.1969811e-6 seconds). 
is a
fitted normalisation constant.
Example - Removing exponential decay:
y = [100, 150, 50, 10, 5]
x = [1,2,3,4,5,6]
input = CreateWorkspace(x,y)
output = RemoveExpDecay(input)
print "Exp. decay removed:", output.readY(0)
Output:
Exp. decay removed: [-0.24271431 0.79072482 -0.05900907 -0.70331658 -0.76614798]
