Table 2
The limits of the priors used in MCMC calculations and in hierarchical models.
| Parameter | Min | Max | Note |
|
|
|||
| μ1 = ⟨ T ⟩ | 5.0 | 30.0 | Expectation value of temperature |
| μ2 = ⟨ β ⟩ | 0.0 | 4.5 | Expectation value of spectral index |
| I i | 0.1 | 10.0 | Intensity of a source/pixel |
| at a reference wavelength | |||
| (No upper limit in the MHD model) | |||
| T i | 5.0 | 30.0 | Temperature of a source/pixel |
| β i | − 6.0 | +6.0 | Spectral index in modified black body tests |
| β i | 0.0 | +4.5 | Spectral index in calculations with MHD |
| Models and Herschel observations | |||
| δ j | 0.3 | 2.5 | Factors for calibration errors |
Notes.Apart from δj (see Sect. 5.1), the priors are flat. The parameters not listed in the table have flat priors without limits.
