Extensive air shower reconstructed by the VERITAS telescopes. The shower images for each camera have been integrated over time and cleaned using a two-level filter. Dead and disabled channels are shown in dark gray and brown respectively. The signal registered by each PMT is color-coded, with red colors representing higher signal than blue tones. An approximate geometrical reconstruction of the shower core location is illustrated with red dashed lines and a red star. The upper right plot shows the trace of one of PMT (#255) of T1 for reference. There, the signal registered for each sample of 2 ns is plotted in red and the integration window (six samples) is shown in shadowed blue.
