Abstract
Incorrect expressions are shown for the Doppler width of spectral lines that occurred in some literature sources that results in different estimates of the corresponding nonthermal velocities. By way of example, it is shown that the values of the nonthermal velocities obtained by Patsouracos and Klimchuk (Astrophys. J., 2006, vol. 647, p. 1452) are overestimated by 30–40% as compared to the true values.
