The U.Hawaii IfA Weak Lensing Group
Weak Lensing Project
We are in the process of obtaining extensive deep, wide-field, multi-color images
of a set of fields distributed around the sky. The primary goal of this survey
is to constrain the spectrum of large-scale mass fluctuations in the
Examples of the
fully reduced images for a selection of fields can be viewed with
this image browser.
One of the examples is the supercluster
MS0302+17 which has been
been subject of a detailed weak lensing analysis, X-ray and photometric
analysis. You can read the
paper and also download
FITS images of the mass, luminosity and
X-ray surface brighness.
Another example field is the
Hawaii Deep Field, which is a
very deep image of the 1/2 square degree patch surrounding the
Hubble Deep Field.
The CFH+WFC+UH8K System
We have characterised the
distortion map and psf
for the CFH+WFC+UH8K optical system.
