本文分析了安装在利物浦望远镜上的RINGO_3偏振仪在三年多的时间里对标准恒星进行的偏振观测。主要目的是测定RINGO_3偏振仪在三个光谱能量范围内的偏振度：蓝光(350-640 nm)、绿光(650-760 nm)和红光(770-1000 nm)。这些观察是在2012年至2016年之间进行的。由于观测系统硬件的改变，1126天的总时间跨度被分成了五个纪元。我们的结果应该应用于用RINGO_3偏振仪进行的所有偏振观测的校准。
We present an analysis of polarimetric observations of standard stars performed over the period of more than three years with the RINGO3 polarimeter mounted on the Liverpool Telescope. The main objective was to determine the instrumental polarisation of the RINGO3 polarimeter in three spectral energy ranges: blue (350--640~nm), green (650--760~nm) and red (770--1000~nm). The observations were conducted between 2012 and 2016. The total time span of 1126 days was split into five epochs due to the hardware changes to the observing system. Our results should be applied to calibrate all polarimetric observations performed with the RINGO3 polarimeter.
