Hi Yannick,

If TP could start sending those data to the CADC now, incrementally,
instead of waiting until close to the deadline, that would greatly
increase the chances of a successful release and greatly reduce the
stress at the CADC. Once you have 'approved' a stack simply place
that data into e-transfer and we will pull the frames to here....
they will not become public until the release but there is not a good
reason to stage the entire dataset before sending any of it to
CADC. If later, during the processing, there is an error found and
you must re-process then you can just send those reprocessed data again.

thanks,

JJ
