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. |
Using the Principal Componentıs space |
