We present measurements of the galaxy bias b and the galaxy-matter cross-correlation coefficient r for the BOSS LOWZ luminous red galaxy sample .
Using a new statistical weak lensing analysis of the Red Sequence Cluster Lensing Survey ( RCSLenS ) we find the bias properties of this sample to be higher than previously reported with b = 2.45 _ { -0.05 } ^ { +0.05 } and r = 1.64 _ { -0.16 } ^ { +0.17 } on scales between 3 \arcmin and 20 \arcmin .
We repeat the measurement for angular scales of 20 ^ { \prime } \leq \vartheta \leq 70 ^ { \prime } , which yields b = 2.39 _ { -0.07 } ^ { +0.07 } and r = 1.24 _ { -0.25 } ^ { +0.26 } .
This is the first application of a data compression analysis using a complete sets of discrete estimators for galaxy-galaxy lensing and galaxy clustering .
As cosmological data sets grow , our new method of data compression will become increasingly important in order to interpret joint weak lensing and galaxy clustering measurements and to estimate the data covariance .
In future studies this formalism can be used as a tool to study the large-scale structure of the Universe to yield a precise determination of cosmological parameters .
