Notes to Table:
 A single proposal can request more than 1 run, e.g. 3 different instruments on 2 different telescopes = 3 runs.
 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.
 Since Australia has no set share of VLT time, the actual oversubscription is only known after the OPC has met.
 Fraction of all OPC-allocatable time on the 4 UTs (including VLTI time) allocated to Australian-led programmes, relative to the time allocated to ESO members states + Australia only. These fractions are calculated by the OPO in Dec each year for the 2 most recently completed Periods. For comparison Australia’s Net National Income is ~7.5% of the total for all ESO member states + Australia.
 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.
 The Period 107 Call for Proposals was canceled due to COVID-19 causing nearly all observing time in Period 105 to be lost.
 Due to COVID no Visitor Mode observations with observers traveling to Paranal were permitted in P105-109, though some Designated Visitor Mode runs were carried out.
ESO supplies AAL with telescope/instrument demand and time allocation data relating to Australian astronomers only to furnish the above statistics. Australian ESO applicant data is used only for statistical purposes, and will only be published or made available to other third parties such as AAL member institutions, in aggregated and anonymised form. Any user who wishes that their data not be used for such purposes is encouraged to contact us.
