普朗克-ATCA共同评估观测（PACO）项目：明亮样本
The Planck-ATCA Co-eval Observations (PACO) project: the bright sample
摘要：
普朗克-ATCA共评观测（PACO）提供了在普朗克频段以下和与普朗克频段重叠的频率上的AT 20 G射电源的明确样本的通量密度测量，几乎与普朗克观测同时进行。我们已经观察到与澳大利亚望远镜紧凑型阵列（ATCA）在4.5和40 GHz之间的频率范围内，在2009年7月至2010年8月期间，共482源。几个来源不止一次被观察到。在本文中，我们提出了该项目的目标，选择标准，观察和数据处理程序。我们还讨论了一个完整的样本的189个源的总强度的数据，S（20 GHz）>500 mJy，银河系纬度|b| > 5度，和decliter <-30度，和一些统计分析的光谱行为和变化的这个样本，被称为“明亮的PACO样本”。最后，我们讨论了这些数据可以用来转移绝对校准地面望远镜使用CMB偶极子校准通量密度测量的普朗克卫星，我们提供了一些测试通量亮校准器。
英文摘要：
The Planck-ATCA Co-eval Observations (PACO) have provided flux density measurements of well defined samples of AT20G radio sources at frequencies below and overlapping with Planck frequency bands, almost simultaneously with Planck observations. We have observed with the Australia Telescope Compact Array (ATCA) a total of 482 sources in the frequency range between 4.5 and 40 GHz in the period between July 2009 and August 2010. Several sources were observed more than once. In this paper we present the aims of the project, the selection criteria, and the observation and data reduction procedures. We also discuss the data in total intensity for a complete sample of 189 sources with S(20 GHz)>500 mJy, Galactic latitude |b|>5deg, and declination <-30deg, and some statistical analysis of the spectral behaviour and variability of this sample, referred to as the "bright PACO sample". Finally we discuss how these data could be used to transfer absolute calibrations to ground based telescopes using the CMB dipole calibrated flux densities measured by the Planck satellite, and we provide some test fluxes on bright calibrators.
