我们使用Tuorla blazar监测计划（KVA DIPOL）和利物浦望远镜（LT）RINGO 2偏振仪（补充SkyCamZ（LT）和费米-LAT γ射线数据）对15颗γ射线亮blazar进行了936天（2008年10月11日至2012年10月26日）的2000次偏振和3000次光度观测。在15个源中的11个中，我们总共识别出19个电矢量位置角（EVPA）旋转和95个耀斑事件。我们根据它们的宽带光谱特性将这些源分成子类，并比较它们观测到的光学和γ射线特性。结果表明：（1）光学星等与γ射线通量呈正相关，（2）EVPA旋转可以发生在任何blazar子类中，四个源都表现出向一个方向旋转并立即旋转回来的现象，（3）我们没有看到样品中γ射线耀斑速率的差异;耀斑可以发生在旋转期间和旋转之外，而不偏好这种行为，（4）平均偏振度（DoP），与非旋转期间相比，在EVPA旋转期间的光学幅度和γ射线通量较低，并且在EVPA旋转期间的DoP分布与旋转外部的分布不是从相同的母样品中得出的，（5）观测到的耀斑事件的数量与光学偏振旋转相关，然而，我们没有发现强有力的证据表明单个耀斑和旋转之间存在时间关联;（6）对于同步辐射峰值分别在高、中、低频率的子类，观测到的最大DoP从10%增加到30%，再增加到40%。
We present ∼2000 polarimetric and ∼3000 photometric observations of 15 γ-ray bright blazars over a period of 936 days (2008-10-11 to 2012-10-26) using data from the Tuorla blazar monitoring program (KVA DIPOL) and Liverpool Telescope (LT) RINGO2 polarimeters (supplemented with data from SkyCamZ (LT) andFermi-LAT γ-ray data). In 11 out of 15 sources we identify a total of 19 electric vector position angle (EVPA) rotations and 95 flaring episodes. We group the sources into subclasses based on their broad-band spectral characteristics and compare their observed optical and γ-ray properties. We find that (1) the optical magnitude and γ-ray flux are positively correlated, (2) EVPA rotations can occur in any blazar subclass, four sources show rotations that go in one direction and immediately rotate back, (3) we see no difference in the γ-ray flaring rates in the sample; flares can occur during and outside of rotations with no preference for this behaviour, (4) the average degree of polarization (DoP), optical magnitude and γ-ray flux are lower during an EVPA rotation compared with during non-rotation and the distribution of the DoP during EVPA rotations is not drawn from the same parent sample as the distribution outside rotations, (5) the number of observed flaring events and optical polarization rotations are correlated, however we find no strong evidence for a temporal association between individual flares and rotations and (6) the maximum observed DoP increases from ∼10 per cent to ∼30 per cent to ∼40 per cent for subclasses with synchrotron peaks at high, intermediate and low frequencies, respectively.
