Distribution of the measured line intensity ratios between pairs of hydrogen RRLs at nearby frequencies as a function of the predicted ratios under LTE conditions. The ratios are labelled and the bars represent 1.5σ errors. The dotted blue line corresponds to equal values between observed and predicted ratios under LTE conditions.
