Positions of the new pulsars determined by SeeKAT, relative to the center of the cluster (the intersection of the horizontal and vertical dashed lines) and the position of NGC 1851A, indicated by the red star. The gray scale background indicates probability density, while the purple, blue and green ellipses represent the 68%, 95%, and 99.7% probability contours, respectively. The black dashed circle indicates the core radius of NGC 1851, located at 0.09 arcmin from its nominal center (Harris 2010). The detections of NGC 1851M were too faint to obtain a reasonable position estimate with SeeKAT. All pulsars are detected with highest S/N in the central beams of all TRAPUM observations.
