Table 19.
Independent and joint estimates (see the main text for a definition) of the fNL parameters of the primordial local shape and the thermal dust bispectrum in the raw Planck 143 GHz temperature map, determined using the Binned bispectrum estimator.
| Shape | Independent | Joint |
|---|---|---|
| Local …… | −64 ± 13 | 8 ± 20 |
| Dust …… | 1.21 ± 0.35 | 1.32 ± 0.52 |
Notes. Uncertainties are 68% CL. Uncertainties in this table only are Fisher forecasts multiplied by a factor larger than 1, which depends on the shape, due to the small breaking of the weak non-Gaussianity approximation in this map. Here, we use the same factors as in Jung et al. (2018), which were determined by comparing the observed errors and Fisher forecasts in the analysis of 100 Gaussian CMB maps to which the dust map was added.
