Line Plot from Scientific Research

The extracted strength of the hyperfine interaction S 0,HF as a function of thet{\theta }_{{{{{\bf{f}}}}}_{{{{\rm{Q}}}}}} . The black line is a fit of the data to a cos 2 ( theta {\theta }_{{{{{\bf{f}}}}}_{{{{\rm{Q}}}}}}) , with a = 2.5 × 10 6 Hz 2 Hz -1 . Data are presented as the fitted values of S 0,HF ( theta B ), with error bars indicating the 1 s.d. uncertainty of the fit.
