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 events)rpi?

Proposal:

Begin DST production immediately

A few tens of pb-1 by end of week

Ask people to begin looking before Christmas
