Generalized feature model significance surveyed over the Modal 2 frequency range 0 <  ω <  350, after marginalizing over the phase ϕ. Top panels: results for the constant feature model (Eq. (15)) with T only (left) and T+E (right), middle panels: for the equilateral feature model (Eq. (18)), and bottom panels: for the flattened feature model (Eq. (19)). The same conventions apply as in Fig. 6. These feature model results generally have lower significance than obtained previously (PCNG15), with polarization data not tending to reinforce apparent peaks found using temperature data only.
