Technology: Visiting Committee – Bologna, Dec 3-5, 2007
2nd key aspect:
growing exigency of actively contributing in developping & optimizing observational strategies & analysis procedures for maximizing the scientific output
modern instrument = hardware + software + science
3rd key aspect:
computer center: astronomers fond of software & software engineers fond of astronomy
