Data tables for above graphs, received from Paul Jorden on 06/02/2001. Note that these are just models and the delivered chips may differ a bit. Note also that the models are for 253K, whereas we will be using the chips at 233K. This means we will see a drop of a couple of per cent in QE, but no real change in shape (according to Paul). The excel spreadsheet from which the table below has been formed can be found here.
