So now we have JD taken care of. There are some other fields in our Observations table that are just taking up space at present Space is an issue. Even if Tom did offer to supply disk drives, wasted space still costs us time.
Extra data has to be moved across some interface for every read and write.
Half a millisecond here and there adds up when you have a few hundred mullion records. Keep then as is. If we keep them then I want to fill them with something usfull. Conversely, If they can't be filled with usfull information I'd like to remove them. From this we could maybe compute sharpness and elipticality but not a possion angle or a saturation flag.
