RATAN-600深RZF调查（1998-2003）中功率波束图的研究
Study of the Power Beam Pattern of RATAN-600 During the Deep RZF Survey (1998-2003)
摘要：
本文提出了一种基于近天顶深空观测过程中NVSS源样本构造RATAN-600实验功率波束图的方法。从观测的9个波段（2002年和2003年）的7.6 cm射电源中获得的数据被用来构建望远镜的垂直PB，该垂直PB与PB的中心水平部分有相当大的偏移（+/-36 '）。使用不同的方法获得的实验PB进行比较，并确定从相应的计算PB的实验PB的均方根偏差。对1998-2003年RATAN-600天顶场（RZF）巡天期间中心部分（+/-6 '）能量束图的稳定性以及在该巡天框架内观测到的并纳入RZF星表的源通量的精度进行了估算。
英文摘要：
This paper proposes a method for constructing an experimental power beam pattern (PB) of RATAN-600 based on the sample of NVSS sources observed in the process of a deep sky survey near local zenith. The data obtained from observations of radio sources at wave 7.6 cm in nine bands of the survey (the 2002 and 2003 sets) are used to construct vertical PB of the telescope at rather large offsets from the central horizontal section of the PB (+/-36'). The experimental PBs obtained using different methods are compared and the root-mean-square deviations of the experimental PB from the corresponding computed PB are determined. The stability of the power beam pattern in its central part (+/-6') during the RATAN-600 Zenith Field (RZF) survey (1998-2003) and the accuracies of the fluxes of the sources observed within the framework of this survey and included into the RZF catalog are estimated.
