 to planet ``p1``. Again, ``juliet`` is able to handle different perturbations for different planets. In our case, then, we will be adding a parameter ``dt_p1_TESS_3``, and will in addition 
 be providing priors for the time-of-transit center (``t0_p1``) and period (``P_p1``) in the system, which will be in turn constrained by the other transits. To do this with ``juliet`` we
