            Paul Price, Robert Gruendl – I'll talk to John Swinbank to see what we can do about person-power. Good point, thanks for raising it (both of you).

            With regard to loss-less compression. I see no reason not to obtain benchmarks but the anecdotal performance I know of when using GZIP_1, I think will preclude it from being a viable candidate at this time (the ultimate reason for this investigation has been to determine whether sufficient compression factors can be achieved to support storing and serving a broader range of reduced LSST image products (e.g. the PVI products) within the data releases.
