1. DST status Ready for production Analysis of sample ksl DST’s in progress for ~1 week ksl DST event size: 2.8 MB/nb -1 560 GB for 200 pb -1 Other streams for which DST’s can be produced: rad? (question about mmg events) rpi? Proposal: Begin DST production immediately A few tens of pb -1 by end of week Ask people to begin looking before Christmas
