In the paper “Transverse dimensions of chorus in the source region” by O. Santolík and D. A. Gurnett, (Geophysical Research Letters, 30(2), 1031, doi:10.1029/2002GL016178, 2003), an error appeared in the abstract (paragraph ). A correction is given here.
 The following statement has to be deleted from the abstract since it does not correspond to the contents of the final version of the paper:
 “The observations are consistent with a statistical model of the source region assuming individual sources as gaussian peaks of radiated power with a common half-width of 35 km perpendicular to the magnetic field. This characteristic scale is comparable to the wavelength of observed waves.”
 Results of the statistical model were not included in the paper due to the length limitations and have been recently published elsewhere [Santolík et al., 2004], but were mistakenly mentioned in the abstract. The removed text should be replaced by the following:
 “The characteristic scale for the decrease of the correlation coefficient is approximately 100 km.”
