Results for the fNL parameters of the primordial local, equilateral, and orthogonal shapes, determined by the suboptimal wavelet estimator from the SMICA foreground-cleaned map.

| Local ......... | 10 ± 8.5 | 0.9 ± 8.5 |
| Equilateral ......... | 89 ± 84 | 90 ± 84 |
| Orthogonal ......... | −73 ± 52 | −45 ± 52 |
Notes. Both independent single-shape results and results marginalized over the point source bispectrum and with the ISW-lensing bias subtracted are reported; error bars are 68% CL. As explained in the text, our current wavelets pipeline performs slightly worse in terms of error bars and correlation to primordial templates than the other bispectrum estimators, but it still provides a useful independent cross-check of other techniques.
