LBL Cosmology Visitor Program 
Weak Lensing workshop 
Day 3 discussions 

* Galaxy-galaxy lensing: probing small scales, profiles, 
flattened halos in observations vs. simulations 

* N-body simulations: "paint galaxies on" and do lensing; 
baryon effects on density profile 

* What good is precision measure of fuzzy quantities, e.g. 
mass?  What is the right meeting ground between observation 
and theory? 

* Halo occupation distribution discussion
