Overview on Active Proposals and Remaining Shifts

Experiments with granted beamtime (i.e. ranked A) are listed in this table. It contains experiments in the status after granting and before completion/expiry, and gives number of granted shifts.

Experiments in the reserve list have been ranked A- due to large overdraft of beamtime. They might be scheduled if beamtime becomes available. 

Data are updated before and after a beamtime block.
