Parity-odd signals (ℓ₁ + ℓ₂ + ℓ₃ = odd) of the TTT (top) and EEE (bottom) bispectra (ℓ_i ≤ 500) recovered from the SMICA maps by means of the Modal decomposition with 101 simple polynomial-based eigenmodes, not including any special functions fitting the CMB tensor-mode features. In the panel for EEE, only the signals larger than ℓ = 40 are shown. The TTT and EEE bispectra shown here are rescaled with a constant Sachs-Wolfe weighting and signal-to-noise weighting, respectively.
