We present the cluster mass-richness scaling relation calibrated by a weak lensing analysis of \ga 18000 galaxy cluster candidates in the Canada-France-Hawaii Telescope Lensing Survey ( CFHTLenS ) .
Detected using the 3D-Matched-Filter cluster-finder of Milkeraitis et al. , these cluster candidates span a wide range of masses , from the small group scale up to \sim 10 ^ { 15 } M _ { \odot } , and redshifts 0.2 \lesssim z \lesssim 0.9 .
The total significance of the stacked shear measurement amounts to 54 \sigma .
We compare cluster masses determined using weak lensing shear and magnification , finding the measurements in individual richness bins to yield 1 \sigma compatibility , but with magnification estimates biased low .
This first direct mass comparison yields important insights for improving the systematics handling of future lensing magnification work .
In addition , we confirm analyses that suggest cluster miscentring has an important effect on the observed 3D-MF halo profiles , and we quantify this by fitting for projected cluster centroid offsets , which are typically \sim 0.4 arcmin .
We bin the cluster candidates as a function of redshift , finding similar cluster masses and richness across the full range up to z \sim 0.9 .
We measure the 3D-MF mass-richness scaling relation M _ { 200 } = M _ { 0 } ( N _ { 200 } / 20 ) ^ { \beta } .
We find a normalization M _ { 0 } \sim ( 2.7 ^ { +0.5 } _ { -0.4 } ) \times 10 ^ { 13 } M _ { \odot } , and a logarithmic slope of \beta \sim 1.4 \pm 0.1 , both of which are in 1 \sigma agreement with results from the magnification analysis .
We find no evidence for a redshift-dependence of the normalization .
