I've been noticing a considerable better quality in images observed in the south e.g. 47Tuc 

Rene, you will get a box with tapes as usual but you WON'T get the CHILE_MAZA data as I could not tape them (the drive needs cleaning again, even though I had put a cleaning tape the night before). I have already asked Juan to make a tape and send it to you asap. The same with Dr. Lu's data.
Regarding Dr. Rubinstein, I have already started copying images of 47Tuc in CTIO_RUBINSTEIN (obs. taken on 991018).

Greetings to everyone,

David
