We present a new measurement of the mass-concentration relation and thestellar-to-halo mass ratio over the halo mass range $5\times 10^{12}$ to$2\times 10^{14}M_{\odot}$. To achieve this, we use weak lensing measurementsfrom the CFHT Stripe 82 Survey (CS82), combined with the central galaxies fromthe redMaPPer cluster catalogue and the LOWZ/CMASS galaxy sample of the SloanDigital Sky Survey-III Baryon Oscillation Spectroscopic Survey Tenth DataRelease. The stacked lensing signals around these samples are modelled as a sumof contributions from the central galaxy, its dark matter halo, and theneighboring halos, as well as a term for possible centering errors. We measurethe mass-concentration relation: $c_{200c}(M)=A(\frac{M_{200c}}{M_0})^{B}$ with$A=5.24\pm1.24, B=-0.13\pm0.10$ for $0.2<z<0.4$ and $A=6.61\pm0.75,B=-0.15\pm0.05$ for $0.4<z<0.6$. These amplitudes and slopes are completelyconsistent with predictions from recent simulations. We also measure thestellar-to-halo mass ratio for our samples, and find results consistent withprevious measurements from lensing and other techniques.
