The background functions

You can take a look at the definitions of the background functions with the command:

[]tv $>$ fit function background definition polynom
$BG(x)= ∑$ _n=0^N B_n ⋅(x-x₀)ⁿ

B_n :
background coefficient (parameter)
x₀ :
offset for numerical optimization during fit
[]tv $>$ fit function background definition exponential
$BG(x)= ∑$ _n=0^N B_n ⋅(x-x₀)ⁿ + FAC ⋅ exp(-(x-x₀)⋅EXP)

B_n :
background coefficient (parameter)
x₀ :
offset for numerical optimization during the fit
FAC:
factor of exponential term
EXP:
scaling of exponential term
