Partner Time Allocation
The expected time allocation to each partner for the current and next semesters is listed in the relevant Call for Proposals.
Partner Time Distribution in 2012
The method for division of telescope time each semester between engineering, instrument Guaranteed Time (GT), campaigns, Science Verification (SV), Observatory host (University of Hawaii or Chile), Director's Discretionary Time, and partner science time is described in the 2013 Partner Shares page. Note that prior to semester 2012A there was a 10% allocation of time for Staff, hence the time available to the six partners (US, UK, CA, AU, BR, AR) in 2012 effectively increased by 5%, compared to pre-12A semesters.
A schematic of the time distribution is given below, right.
The Table below illustrates two example cases of time allocation. In Example 1, 10% of the total available time goes to engineering, and 55 hours goes to GT, campaign and SV time. In Example 2, 14% of the total available time goes to engineering, and 180 hours goes to GT, campaign and SV time. For computational convenience it is assumed that there are 10 hours available per night on average.
Partner | Nominal Fraction | Example 1 Allocation (hours) | Example 2 Allocation (hours) | Effective Fraction |
US | 43.91% | 643 | 562 | 40.84% |
UK | 22.00% | 322 | 282 | 20.46% |
CA | 13.86% | 203 | 177 | 12.89% |
AU | 5.72% | 84 | 73 | 5.32% |
BR | 2.31% | 34 | 30 | 2.15% |
AR | 2.20% | 32 | 28 | 2.05% |
Host (Hawaii/Chile) | 10.00% | 157 | 138 | 10.0% |
DDT | 7% | 99 | 87 | 6.3% |
