We collected optical ($RIZ$) and near-infrared ($YJHK_{\\rm s}$) linear polarimetry images on various time scales from $\\sim$0.2 h to months. Linear polarization degrees in the interval 0-1.5\\% ($I$- and $J$-bands) were measured with accuracies ranging from $\\pm$0.1 $\\%$ to $\\pm$0.9 $\\%$ depending on the observing filter and the target brightness.
