 # Arguments
 - `bp::Pitchfork` the bifurcation point
-- `ds` at with distance relative to the bifurcation point do you want the prediction. Based on the criticality of the Picthfork, its sign is enforced no matter what you pass. Basically the parameter is `bp.p + abs(ds) * dsfactor` where `dsfactor = ±1` depending on the criticality.

 # Optional arguments
 - `alg = br.alg` continuation algorithm to be used, default value: `br.alg`
 - `δp` used to specify a specific value for the parameter on the bifurcated branch which is otherwise determined by `options_cont.ds`. This allows to use a step larger than `options_cont.dsmax`.
