Weak lensing

Weak Lensing

Our pre-measured weak gravitational lensing shear catalogue is not publicly available, because subtleties in the measurement of shears, photometry and photometric redshifts must be carefully considered to maintain quality control. However, we are very happy to collaborate with people wanting to use the catalogue, and can work with you to optimise its use. If you would like to work with us, please contact Alexie LeauthaudRichard Massey and Jason Rhodes.

However, we have released high-level data products and various low-level software tools that grew out of our precision lensing analysis but may be useful for generic HST image processing.
