Abstract : We present the results of a deep near-infrared imaging survey of the Serpens Cloud made with FLAMINGOS at the 2.1 m telescope at Kitt Peak National Observatory. We modify the algorithms used to identify clusters. The conventional Nearest Neighbor Method may exclude stars from the cluster edge. Hence we propose necessary modifications for the algorithm. We propose the use of a modified Nyquist box to calculate and represent cluster parameters as well. We study the distribution of young embedded sources using the nearest neighbor method applied to a carefully selected sample of near-infrared excess (NIRX) stars that trace the latest episode of star formation in the complex. Our analysis finds the existence of six clusters, of which three are new in the molecular cloud. The new cluster identified were verified using the UKIDSS data, was missed also by c2D. We study the distribution of Class 0/I, II and III sources in the cloud and using ratio maps study the progress of star formation in the cloud using Spitzer c2D data. We determine a median age for the cluster to be 1-2 Myr at a mean distance of 300 pc.We construct extinction maps for the Serpens star cluster. We study the overall star formation in Serpens by comparing the properties of individual clusters with those of the Rosette Cloud and others.
