    Hello All,
    We here at LBL have been working on a reduction pipeline to stack all of
    the observations for each cluster into one deep image. We have
    established a new directory on each web page named "stack", and are
    moving the deep images into this directory. We have already done
    several clusters, and hope to have a dozen or so by tommorrow. These
    images are not yet the final product, we believe there is a residual
    distortion remaining in the images, causing incomplete registration over
    different epochs. We believe the RMS scatter is better then 0.1 pixels
    between different epochs. We will continue to post the most recent
    version of our reduction in this directory as it becomes available, and
    I will send out an email notifying everyone when we have that, with
    links to the description of the technique and the data reduction package
    itself when we converge on a final product. For now, I'd like to
    request that you take a look at the most recent version, and feel free
    to use this data for a preliminary analysis for the HST proposal.

    -Kyle
