Description
An analysis is presented of high-resolution high SNR spectra of
late-type chromospherically active dwarfs in Ca II H. Observational
parameters employed are the total emission flux attributable to the
chromosphere, the asymmetry of the emission component and its bisector,
the ratio of the intensities of the blue and red H2 emission peaks, and
the absolute wavelengths of the H3 minimum and the mean emission
feature. Given time-spaced sets of spectra for each object, which are as
yet relatively sparse, the potential use of these observational
parameters to deepen understanding of the chromospheric activity is
explored.
