From TESS data, we extract 69 frequencies and determine $\\Delta\\nu \\simeq 82$ $\\mu$Hz. Rotating MESA models are computed at low and high resolution; their pulsation frequencies are calculated with GYRE (adiabatic/non-adiabatic, first-order rotation) and FILOU (adiabatic, second-order rotation).\n  Using $\\Delta\\nu$ as a structural constraint is necessary to reduce model degeneracy.
