2 Outline General advice on planning any (ground based) observation NRAO telescopes: the GBT, ALMA, VLBA, and in particular the, VLBA and ALMA are radio frequency interferometers, GBT is a single radio dish ALMA is a joint endeavor (i.e. somewhat special with its own rules) Specific advice for planning observations (I): Proposing Planning starts before proposing/applying for time Introduction to the web-based tool to apply for NRAO telescope time Proposal Submission Tool (PST) found at Specific advice for planning observations (II): Scheduling Operations and logistics: dynamic scheduling and scheduling priorities Creating observing schedules is about determining the optimum trade-offs (for YOUR science case) Introduction to the web-based tool to schedule observations Observation Preparation Tool (OPT) through PST or via Planning () Observations,2014 th NRAO Synthesis Imaging Workshop 2

4 Location of the telescope Determines what part of the sky is visible Declination range, e.g., for the : -44 to +90 Planning any (ground based) observation Determines the dry/wet seasons and other weather and atmospheric related issues (e.g., troposphere and ionosphere) Determines the level of interfering human activities (light pollution, radio frequency interference) Particular telescope may have closures (e.g., maintenance) or instrumentation may be unavailable for periods of time, usually well announced Planning () Observations,2014 th NRAO Synthesis Imaging Workshop 4
5 Planning any (ground based) observation Scientific and technical justification Operating telescopes costs money; observing time is precious! Time is available for well justified (scientific) projects on a competitive basis Scientific justification (next slide) should clearly outline the broader scientific relevance and define goals that outline why only (new) telescope time using this particular instrument on a specific target will achieve that goal and contribute to the general knowledge of the research topic Technical justification is to demonstrate that the choice of instrumentation, the observing time and the proposed methodology will yield the result using the requested resources in the most optimal way (i.e., within reason) Projects are ranked by committees based on scientific and technical merit but even a top-notch scientific case may end up without observing time if the justification is poorly argued or technically not feasible Conditional to constraints known to the TAC (time/resources available, day/night and other operational conditions, competition) Planning () Observations,2014 th NRAO Synthesis Imaging Workshop 5
6 Scientific and technical justification Why? Science context and motivation: what makes this subject scientifically interesting for the field? Outline the broader impact of the science topic and the importance for astrophysics What? Specific science questions: what missing but obtainable knowledge is furthering the field? How? Specific science goals: how are these observations, resulting observables, going to answer the questions above and how will the science goals be achieved by this program? Planning () Observations,2014 th NRAO Synthesis Imaging Workshop 6
7 Scientific and technical justification Must appeal to non-expert astrophysicist reviewer (try to avoid all jargon!) Who? Target selection criteria: why are these object chosen for the observations, can the sample be smaller, can it instead be done with similar sources at less popular LST ranges? When and where? Should this wait for a better opportunity, hosted by another telescope, that is, why now and why this telescope? What is needed? Resources such as instrumental setups, observing time, operational conditions, data reduction requirements Show it can be done! Planning () Observations,2014 th NRAO Synthesis Imaging Workshop 7
