| Abstract
| - Aims. The aim of the present work is to study the overall mass distribution of the galaxy clusters Abell 1351 and Abell 1995 using weak gravitational lensing. These clusters have a very different mass structure and dynamical state and are the two extremes from a larger sample of 38 X-ray luminous clusters of similar size and redshift. Methods. We measure the shear values of faint background galaxies and correct for PSF anisotropies using the KSB+ method. Two-dimensional mass maps of the clusters are created using a finite-field mass reconstruction algorithm, and verified with aperture mass statistics. The masses inferred from the reconstructions are compared to those obtained from fitting spherically symmetric SIS- and NFW-models to the tangential shear profiles. We discuss the NFW concentration parameters in detail. Results. From the mass reconstructions we infer $M_{\rm 2D}(<r_{200})$-masses of $11.7\pm3.1\times10^{14}\,h_{70}^{-1}~M_odot$ and $10.5\pm2.7\times10^{14}\,h_{70}^{-1}~M_odot$ for Abell 1351 and Abell 1995, respectively. About $3\arcmin$ northeast of the main mass peak of Abell 1351, we detect a significant secondary peak both in the mass reconstruction and from aperture mass statistics. This feature is also traced by cluster members selected by means of their $V-I$ colour, and is therefore likely a real substructure of Abell 1351. From our fits to the tangential shear we infer masses of the order of $M_{200}\sim8{-}9\times10^{14}~h_{70}^{-1}~M_odot$ (Abell 1351) and $M_{200}\sim5{-}6\times10^{14}~h_{70}^{-1}~M_odot$ (Abell 1995). The concentration parameters remain poorly constrained by our weak lensing analysis.
