# limit


Under this identifier are defined the priors on the potential parameters. It is advised to put the limit identifier just after the potentiel identifier. As the potential identifier, it is allowed to put comments after the identifier limit on the same line.




## x\_centre int float1 float2 float3


Gives limits for the `x_centre` parameters of the deflecting potential, when using the inverse mode. 

`int` tells if and how should the optimizer handle the parameters. 0: the optimizer does not change the parameter, and keep the value defined within the potential list. 1: consider a flat prior with strict bounds `float1` and `float2`. 3: consider a Gaussian prior with mean `float1` and dispersion `float2`.

Outdated: 
`float1` is the minimum. `float2` is the maximum. `float3` is the precision desired on the parameters, be careful it is not a dispersion! 
2: consider `float1` and `float2` as soft bounds. If the optimizer find a minimum outside this bounds, it will test it. 3: consider `float1` as a soft bound, `float2` as strict bound. 4: consider `float2` as a soft bound, `float1` as strict bound. -n: the optimizer will take n different values between `float1` and `float2`, and try to optimize the others parameters. Only 2 parameters can have such limit mode.
