We can not provide you with this data for the simple reason that we do
not archive the data prior to correlation.

Even if the data were available, it would be impractical for you to deal
with it: you would need a considerable amount of expensive equipment to
read the data from tape and to interpret it. In addition, the pre-correlated
data is large: of the order of 1 terabyte per antenna per experiment.
