Statistical analysis for precise estimation of structural properties of
  NGC 1960
  The statistical analysis of gathered of astronomical objects (such as open
cluster) are excellent tools to compute its parameters and to constrain the
theory of its evolution. Here, we are represented detailed structural and
membership analysis of an open cluster NGC 1960 through various statistical
formulas and approaches. King empirical methods provide the information about
the cluster extent as 5.2 +/- 0.4 pc. The exact identification of members of
cluster is needed to precise estimation of its age, reddening, metallicity
etc., therefore, to identify most probable members (MPMs), we adopted the
combined approach of various statistical methods (kinematic, photometric and
statistical) and 712 members are satisfied needed criteria of MPMs. The basic
physical parameters of the cluster such as E(B-V)=0.23+/-0.02 mag,
E(V-K)=1.05+/-0.03mag, log(Age)=7.35+/-0.05, and (m-M)=11.35+/-0.10 mag are
obtained using the color-color and color-magnitude diagrams. NGC 1960 is found
to be located at a distance of 1.34 +/- 0.03 kpc. Using the archival proper
motion catalogues, we estimate mean proper motions of NGC 1960 as 0.83+/-0.26
mas yr-1 and -6.55+/-0.23 mas yr-1 in the direction of RA and DEC,
respectively.
