Abstract:
Equivalent widths for a new lines of the first overtone band of carbon monoxide have been calculated in the solar infrared spectrum for five facular and two photospheric models. The calculations show a decrease in equilavent withds in the facular models of Stellmacher & Wiehr (1973), Stenflo (1975) and Chapman (1979) and an increase in the models of Schmahl (1967) and Shine & Linsky (1974). The modles are also discussed in the light of Polonskij's (1966) and Tsuji's (1977) observations.
