A detailed optical and infrared photometric analysis of the open star cluster IC 361 is given in the present paper. On studying the radial density profile, radial extent of the cluster is found to be \(8.0\pm 0.5\) arcmin. The basic physical parameters of the cluster such as \(E(B-V) = 0.56\pm 0.10\) mag, \(E(V-K)=1.72\pm0.12\) mag, \(\hbox {log(Age)}=9.10\pm 0.05\), and \((m-M)_{0} = 12.54\pm 0.05\) mag are obtained using the colour–colour and colour–magnitude diagrams. IC 361 is found to be located at a distance of \(3.22\pm 0.07\) kpc. Using the archival proper motion catalogues, we estimate the mean proper motions of IC 361 as \(4.97\pm 0.17\) mas yr\(^{-1}\) and \({-}\,5.80\pm 0.18\) mas yr\(^{-1}\) in the direction of RA and Dec, respectively. A uniform distribution of mass between small scale and large scale is confirmed by MF slope of IC 361. However, the mass function slope of cluster region is found to be \(-1.06\pm 0.09\), which is too low compared to the Salpeter value. Our study is further showing a dynamical relaxation behaviour of the cluster IC 361.

本文给出了对开放星团IC 361的详细光学和红外光度分析。通过研究径向密度分布，发现簇的径向范围为\（8.0 \ pm 0.5 \） arcmin。群集的基本物理参数，例如\（E（BV）= 0.56 \ pm 0.10 \） mag，\（E（VK）= 1.72 \ pm0.12 \） mag，\（\ hbox {log（Age）} = 9.10 \ pm 0.05 \）和\（（mM）_ {0} = 12.54 \ pm 0.05 \） mag是使用彩色图表和彩色图表获得的。发现IC 361位于\（3.22 \ pm 0.07 \） kpc的距离处。使用存档的正确运动目录，我们估计IC 361的平均正确运动为\（4.97 \ pm 0.17 \） mas yr\（^ {-1} \）和\（{-} \，5.80 \ pm 0.18 \） mas yr \（^ {-1} \）分别沿RA和Dec方向。IC 361的MF斜率证实了质量在小规模和大规模之间的均匀分布。但是，发现簇区域的质量函数斜率为\（-1.06 \ pm 0.09 \），相比于Salpeter值。我们的研究进一步显示了集群IC 361的动态弛豫行为。
