  "abstract": "We present the study of dynamical status of the globular cluster NGC 1851. A combination of multiwavelength space and ground-based data sets are used for the present analysis. In order to select the genuine cluster members, we used the astro-photometric data available from HST and GAIA-DR2 catalogs. The BSS radial distribution of the cluster is plotted from the center of the cluster to the outskirts. The radial distribution of BSS shows a central peak, followed by a dip at the intermediate radii (rmin ~ 90'') and a rising trend in the outskirts. We also estimated A+rh parameter as 0.391 +/- 0.006 to validate the findings of the radial distribution study. On the basis of the minima in the BSS radial distribution and the value of A+rh parameter, we conclude that NGC 1851 belongs to Family II classification and is an intermediate dynamical state cluster.",
