Example of the trajectory of deviations δL gaρ (α ep , β eq , t, Δt). We show an example of the behavior of the trajectory of deviations δL gaρ (α ep , β eq , t, Δt). This is obtained by subtracting at each time t, the value of the reference trajectory \( {L}_{ga}\left(\widehat{\alpha},\ \widehat{\beta},t,\varDelta t\right) \) from the average of the values of the different trajectories L ga (α ep , β eq , t, Δt) produced by a fixed value of the parameter change index ρ(p, q). This average is denoted by means of the symbol 〈L ga (α ep , β eq , t, Δt)〉 ρ (cf. Equation (11)). The number of days between sampling times is 15
