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.
