Abstract (from CDS):

We analyze individual pulses detected from RRAT J1819-1458. From April 2007 to April 2010, we carried out observations using the Nanshan 25-m radio telescope of Urumqi Observatory at a central frequency of 1541.25MHz. We obtain a dispersion measure DM=195.7±0.3pc/cm3 by analyzing all the 423 detected bursts. The tri-band pattern of arrival time residuals is confirmed by a single pulse timing analysis. Twenty-seven bimodal bursts located in the middle residual band are detected, and, profiles of two typical bimodal bursts and two individual single-peak pulses are presented. We determine the statistical properties of SNR and W50 of bursts in different residual bands. The W50 variation with SNR shows that the shapes of bursts are quite different from each other. The cumulative probability distribution of intensity for a possible power law with index α=1.6±0.2 is inferred from the number of those bursts with SNR≥6 and high intensities.
