Can anyone provide me with (or point me to) real life gravitational lensing data that I can plug in to the first equation on this page (the standard lensing equation): http://en.wikipedia.org/wiki/Gravitational_lens together with the luminous mass and distance to the galaxy(s). I've looked for papers online and have not found any simple data that can be readily plugged in to the equation (I am not familiar with the details of how exactly the lensing is measured and have gotten lost in the mountains of data in the papers). Thanks
