For the 2025A semester, proposals will be reviewed by a Time Allocation Committee whose members have expertise in various fields of Time Domain Astronomy.
For the 2023A through 2024B semesters, every non-Key-Project proposal was subjected to "Distributed Peer Review" (DPR). Rather than having a small panel of experts read and review a large number of proposals, we had each member of a large panel of experts read and review a small number of proposals in her/his area of expertise. We assembled this panel from members of the LCO community. Specifically:
