Fig. 13.
Comparison of the relative differences between the observed equivalent widths and those calculated using synthetic spectra. Spectral lines of the same ion are plotted with the same symbol. The slope of the least-squares linear fit (continuous line) represents the temperature variation along the pulsational cycle in units of 300 K.
