On the polarization in the solar atmosphere and how CLASP will measure it
[Abstract]
Following some comments from my previous colloquium I think it is a good time to review in more details how the polarization is created by anisotropic illumination in the solar atmosphere and how the Hanle effect modifies this atomic polarization. I will also explain the measurement strategy behind our instrument (CLASP) and how it was calibrated to measure the Hanle effect of the Lyman-alpha line.
