Identification of Stellar Sequences in various Stellar Systems :
  ESO65-SC03, TEUTSCH 106, TURNER 6
  The spatial morphological study of studied clusters is carried out through
the identified probable members within them. The field stars decontamination is
performed by the statistical cleaning approach (depends on the magnitude and
colour of stars within the field and cluster regions). The CMRD (colour
magnitude ratio diagram) approach is used to separate stellar sequences of the
cluster systems. The age, distance and reddening of each cluster are estimated
through the visual inspection of best fitted isochrone in colour magnitude
diagrams(CMDs). The mean proper motion values of clusters are obtained through
the extracted data from PPMXL and UCAC4 catalogs. Moreover, these values are
varying according to the extracted data-set from these catalogues. This
variation is occurred due to their different estimation efficiency of proper
motions. The TCR (two colour ratio) and TCMR (two colour magnitude ratio)
values of each cluster are determined by utilizing the WISE and PPMXL
catalogues, these values are found abnormal for TEUTSCH 106. In addition, the
TCMR values are similar to TCR values at longer wavelength, whereas both values
are far away to each other at shorter wavelength. The fraction of young stellar
objects (YSOs) is also computed for each cluster.
