Abstract

In this paper we present the RATAN-600 multi-frequency catalogue of blazars, an updated version of the BLcat: the RATAN-600 multi-frequency catalogue of BL Lacertae objects. The main novelty in the catalogue is an extension of the sample with flat-spectrum radio quasars (FSRQs), thus currently it contains more than 1700 blazars of different types. The main feature of the BLcat is a compilation of radio continuum data for blazars based on the RATAN-600 quasi-simultaneous measurements at frequencies of 1.2, 2.3, 4.7, 7.7/8.2, 11.2, and 21.7/22.3 GHz. We additionally supplement the catalogue with the radio data from external sources to provide an opportunity to more complete study of radio spectra and radio light curves. For the convenience of users, we developed tools to calculate the spectral index, variability index, and radio luminosity. We briefly describe basic radio properties of blazar subsamples of the catalogue: spectral classification, spectral indices, flux density variability, and radio luminosity.

RATAN-600 耀变体多频目录—BLcat

摘要

在本文中，我们介绍了 RATAN-600 耀变体多频目录，这是 BLcat 的更新版本：BL Lacertae 天体的 RATAN-600 多频目录。目录中的主要新颖之处在于扩展了具有平谱射电类星体 (FSRQ) 的样本，因此目前它包含 1700 多个不同类型的耀变体。BLcat 的主要特点是基于 RATAN-600 在 1.2、2.3、4.7、7.7/8.2、11.2 和 21.7/22.3 GHz 频率下的准同步测量，汇编了耀变体的无线电连续谱数据。我们还使用来自外部来源的无线电数据补充目录，以便提供更全面研究无线电光谱和无线电光变曲线的机会。为了方便用户，我们开发了计算光谱指数、变异指数和射电光度的工具。
