Notes to Table:
[1] A single proposal can request more than 1 run, e.g. 3 different instruments on 2 different telescopes = 3 runs.
[2] A Large Programme is one requiring a minimum of 100 hours of ESO telescope time, spread over 1 to 4 Periods. From Period 104 onwards, Large Programmes may only be submitted in even-numbered Periods.
[3] Since Australia has no set share of VLT time, the actual oversubscription is only known after the OPC has met.
[4] Fraction of all OPC-allocatable time on the 4 UTs (including VLTI time) allocated to Australian-led programmes. Since ~20% of VLT time goes to Chile, ESO staff, and PIs from non-member states, Australia's share of VLT time relative to ESO members states could be slightly greater than these numbers.
[5] New programs only; does not include the 114 hr of Australian Priority A programs from P105 carried over into P106 due to COVID shutdown, as well as the remaining 224 hrs of the MAGPI Large Program allocation from P104.
