Abstract

Abstract We present the third data release from the Parkes Pulsar Timing Array (PPTA) project. The release contains observations of 32 pulsars obtained using the 64-m Parkes ‘Murriyang’ radio telescope. The data span is up to 18 yr with a typical cadence of 3 weeks. This data release is formed by combining an updated version of our second data release with $\sim$ 3 yr of more recent data primarily obtained using an ultra-wide-bandwidth receiver system that operates between 704 and 4032 MHz. We provide calibrated pulse profiles, flux density dynamic spectra, pulse times of arrival, and initial pulsar timing models. We describe methods for processing such wide-bandwidth observations and compare this data release with our previous release.

帕克斯脉冲星定时阵列第三次数据发布

摘要:本文介绍了帕克斯脉冲星定时阵列(PPTA)项目的第三次数据发布。该新闻稿包含了使用64米帕克斯“Murriyang”射电望远镜获得的32颗脉冲星的观测结果。数据跨度可达18年，典型的节奏为3周。此数据发布是通过将我们的第二个数据发布的更新版本与主要使用在704和4032 MHz之间运行的超宽带接收器系统获得的3年最新数据相结合而形成的。我们提供校准的脉冲轮廓，通量密度动态谱，脉冲到达时间和初始脉冲星定时模型。我们描述了处理这种宽带观测的方法，并将此数据发布与以前的发布进行了比较。
