5 Proprietary Period (12 months) Accessible by anyone

6 Proprietary Period (12 months) Most of Cycle 0 data (>100 projects) are publicly available now.

7 Publication with ALMA Archive As of (ALMA publication statistics) 1/3 of ALMA publications are based on archival data. There are only a few papers based on Cycle0 archival data.
