Abstract

There were two errors present in the published article. On page 2, the sentence Their corresponding mode numbers are estimated to be ((m/n ≈ 2/1), (m/n =?/1), (m/n ≈ 2, 3/2), (m/n ≈ -2/-2) by toroidal and poloidal Mirnov coils'. Should instead be Their corresponding mode numbers are estimated to be n = 1, n = 1, n = 2, n = -2 by two carefully calibrated toroidal Mirnov probes. And the sentence 'But the poloidal probes estimated m-number is not as precise as the n-number so that they are used here only for reference value. And the question mark for 220 kHz is because its m-number is not detected by the poloidal probes.' should be deleted. On page 3, the sentence The low frequency mode 125 kHz with m/n ≈ 2/1 is supposed to be located in the middle of the plasma and high frequency modes 250 kHz with m/n ≈ 2, 3/2 and 320 kHz with (m/n ≈ -2/-2) are supposed to be near the center of the plasma should be deleted. The results of our paper remain unaffected.
