STATISTICAL LINE BLANKETING IN ARCTURUS I. BLANKETING-COEFFICIENT DESCRIPTION OF OBSERVATIONS

Abstract

A statistical description of line blanketing is presented for Arcturus (α Boo, K2 IIIp, v = + 0.06) which is based on equivalent widths and identifications of roughly 10,000 spectral lines within the wavelength region λλ3600-25,000 Å. Equivalent-width contributions or blanketing coefficients for lines grouped as to equivalent width and identification are given for 100 Å wavelength intervals for λ < 9000 Å and 500 Å intervals for λ > 9000 Å (Tables I and II). Strong lines are listed individually (Table III), and the variation or scatter of blanketing within intervals is described. Corrections to this description for limitations in the observations and their analysis are discussed.
