| Slide 5 |
| Slide 6 |
| 1: Fix a given dipolar + quadrupolar configuration and compute consistently the thermal map of the surface |
| 2: build an archive of Atmospheric models at different T, B, a (magnetic inclination angle) |
| Slide 9 |
| Effects of radiative beaming: |
| Principal Component
analysis. A grid of 78000 models varying Bquad_i and the LOS, magnetic angles |
| Can we identify families of
³similar² curves in the parameter space? Cluster analysis. |
