Band oscillator strengths for CO transitions between the electronic states A(1)II and X(1) Sigma(+) were measured via absorption with a synchrotron radiation source. When referenced to the well-characterized (5, 0) band oscillator strength, our relative values for the (7, 0) to (11, 0) bands are most consistent with the recent experiments of Chan et al. and the theoretical predictions of Kirby & Cooper. Since the results from various laboratory techniques and theory now agree, analyses of interstellar CO based on absorption from A-X bands are no longer hindered by uncertainties in oscillator strength.
