Description

Observing eruptive prominences and other coronal structures,
Metis provides the intenzity maps in the hydrogen Lyman-alpha
line. Based on theoretical models of the Lyman-alpha formation,
we demonstrate a close correlation between the integrated line
intensity and plasma emission measure where the latter depends on
the effective thickness of the considered structure and its
electron density. Such a correlation varies with the plasma
temperature, providing a useful diagnostics tool.
