Counterparts to such clusters can not be identified without deep NIR data and as such the total of =1deg2 of J , H & Ks band imaging provided by WIRDS is an indispensable tool in such work. Using public XMM X-ray data, we identify extended X-ray sources in the two fields. The resulting catalogue of extended X-ray sources was analyzed for optical/NIR counterparts, using a red-sequence algorithm. Redshifts of candidate groups and clusters were estimated usi","authors_text":"A. Finoguenov, C. J. Willott, C. S. Stalin, E. Daddi, H. J. McCracken, J. P. Kneib, K. Nandra, M. Tanaka, O. Ilbert, O.
