Proposing for VLA and VLBA Time Twelfth Synthesis

Proposing for VLA and VLBA Time Twelfth Synthesis Imaging Workshop Lorant Sjouwerman 2010 June 8-15 National Radio Astronomy Observatory, Socorro NM Outline NRAO VLA NRAO VLBA Proposal writing Generic Science goal Requirements Other considerations VLA and VLBA (and GBT)

NRAO call for proposals VLA configurations and VL(B)A dynamic scheduling Proposal Submission Tool (PST) Regular proposal submission process Other Proposal Types and Routes Proposing for VLA and VLBA Time - Webinar, 2012 June 11 2 Generic: science goal Start with a scientific idea and target list Draft a scientific justification: what and why Write to astrophysically-literate but non-expert reviewers Give science context and motivation Pose specific science questions State specific science goals Describe target selection criteria Say how the proposed observations will Answer the science questions Achieve the science goals Be quantitative !

Proposing for VLA and VLBA Time - Webinar, 2012 June 11 3 Generic: requirements Draft a technical justification: how Angular resolution (longest projected baseline required) Largest angular scale (shortest projected baseline required) (redshifted) Observing frequency, Stokes parameters (polarization) Spectral resolution and bandwidth coverage, e.g., lineof-sight velocity Elevation limits and snapshot or full uv-coverage Sensitivity: use (online) sensitivity calculators! In the image (dynamic range and signal to noise ratio on target) On a baseline (for calibration, self-calibration) Be quantitative ! Flexibility, or what are the possible trade-offs? Proposing for VLA and VLBA Time - Webinar, 2012 June 11 4 Generic: other considerations

Enough field of view? Primary beam attenuation; single field or mosaic? Time and bandwidth smearing affect sources at the edge of the field Nearby calibrators? Need to find better ones, are there other lists to be used? Optimal timeframes? Time of day (night versus day observing, maintenance/RFI) Season (summer, winter) Is the required configuration observing mode offered for this cycle? Solar activity, planet positions, other.. Data reduction plan for large data sets Cover sheets: 5 Proposing for VLA and VLBA Time - Webinar, 2012 June 11

Consult collaborators, abstract, student support VL(B)A (and GBT): Call for Proposals See NRAO Call for Proposals at Proposal deadlines at 5pm Eastern Time on 1st of February, for observing during about July through December 1st of August , for observing during about January through June Call for proposals issued about 3-4 weeks before each deadline Occasional out-of-cycle calls for special opportunities Everyone can apply for NRAO time (open skies policy) If you are interested in applying for time Read the call for proposals! It contains the latest updates; things do change Planned capabilities offered Special opportunities offered Proposing for VLA and VLBA Time - Webinar, 2012 June 11 6 VLA Configuration and dynamic

scheduling Upcoming VLA configurations at adlines This1st of August: D, DnC, C (smaller configurations, up to 1 or 3 km) 12A and 12B: 13A daytime: late LST (R.A.) Both VLA and VLBA use dynamic scheduling Range of starting times Calibration and overhead included in your scheduling blocks Include calibration and overhead in the observing time request Depending on the science this can be anywhere from 7 for VLA and VLBA Time - Webinar, 2012 June 11 20Proposing to >50% Proposal Submission Tool (PST) Prepare a PDF file using any editor to include

The scientific and technical justification (i.e., what, why and how) The combined PDF file should meet the requirements: Content, minimum font size, maximum number of pages Up to 4 pages for a regular proposal (total, including figures, etc.) Up to10 pages for a large proposal (~200 or more NRAO hours) Access the NRAO PST at Register and invite co-authors to register (required!) Select VLA, VLBA, GBT (and further select any joint combination) Fill out the cover sheets and abstract, and attach the PDF file Numbers (etc.) in cover and justification text should match! InclusionProposing of a NRAO staff co-author is optional
