在探测相关中子星脉冲射电辐射的活动中，帕克斯望远镜先前观测到了四颗超新星遗迹和四颗异常X射线双星。在这些数据的原始检索中未检测到信号。我用最近开发的HEIMDALL和FETCH软件包重新处理了数据，这些软件包针对单脉冲检测和分类进行了优化。在这项新的分析中，在0到104 pc cm−3的色散测量范围内，没有从任何目标中检测到信噪比超过7的天体物理脉冲。我包括计算的单无线电脉冲从这些目标的注量限制。
Four supernova remnants and four anomalous X-ray pulsars were previously observed with the Parkes telescope in a campaign to detect pulsed radio emission from associated neutron stars. No signals were detected in the original searches of these data. I have reprocessed the data with the more recently developed HEIMDALL and FETCH software packages, which are optimized for single-pulse detection and classification. In this new analysis, no astrophysical pulses were detected having a signal-to-noise ratio above 7 from any of the targets at dispersion measures ranging from 0 to 104 pc cm−3. I include calculated fluence limits on single radio pulses from these targets.
