Abstract
Area scans with the multi-channel magnetograph at the Kitt Peak McMath Telescope provided simultaneous measures of equivalent widths in two Mn lines, continuum intensity and longitudinal magnetic field component. Observations were carried out with apertures of 2.5″ × 3.5″ arc and 1″ × 1″ arc. For the network elements, which were identified using the magnetic field as tracer, we developed relationships betweenI Continuum,W λ V Doppler and longitudinal field strength. With a minimum of assumptions it is possible to write from these observed relations an expression connecting true temperature perturbation in the line forming layers of the network to true longitudinal field strength. The results provide some constraints upon possible network models.
