The improvement of the calibration relation for determining the size of the broad-line region from the observed optical luminosity of active galactic nuclei (AGN) is a necessary task to study fundamental parameters of distant AGNs such as mass of the central supermassive black hole. The most popular method of the BLRsize estimation is the reverberation mapping based onmeasuring the time delay between the continuum flux and the flux in the emission lines. In our work, we apply the method of photometric reverberation mapping in medium-band filters, adapted for observations at the Zeiss-1000 telescope of the SAO RAS, for the study of AGN with broad lines in the range of redshifts 0.1 < z < 0.8. This paper describes the technique of observations and data processing, provides a sample of objects and demonstrates the stability of the used method. As a preliminary result for 2MASXJ08535955+7700543 at z = 0.1 we have obtained time delay estimates of τ(ICCF) = 32.2^±10.6 days and τ(JAVELIN) = 39.5_−15.8^+23.0 days that are consistent with each other and also within the accuracy of the existing calibration relations.

0.1 <z <0.8时AGN的光度混响映射。一，观测技术

根据观测到的活动银河核（AGN）的光度，确定宽线区域大小的校准关系的改进是研究遥远AGNs基本参数（例如中央超大规模黑洞质量）的必要任务。BLR大小估计的最流行的方法是基于测量连续通量和发射线通量之间的时间延迟的混响映射。在我们的工作中，我们将中频带滤波器中的光度混响映射方法（适用于SAO RAS的Zeiss-1000望远镜的观测结果）应用于AGN的研究，其红线范围在0.1 < z<0.8。本文介绍了观测和数据处理技术，提供了一个对象样本并演示了所用方法的稳定性。作为2MASXJ08535955 + 7700543在z = 0.1时的初步结果，我们获得了时间延迟估计值τ（ICCF）= 32.2 ^±10.6天，τ（JAVELIN）= 39.5 _-15.8 ^+23.0天彼此一致，并且在现有校准关系的准确性。
