  1. WASP getting started

  2. Horne 2006

  3. Mass-Radius Relation Radius and inclination from transits Mass from inclination and radial velocity

  4. Aperture Horne 2002

  5. Optics: sky coverage and depth 1% of sky with 1 CCD WASP LSST 11cm aperture 16 CCDs 2.5% of sky 8m aperture - 750 CCDs – 0.02% of sky

  6. 11cm aperture; f/1.8 16 CCDs; 1000 sqr deg

  7. Survey Grasp

  8. INT Parameter Space VST • For flat logN-logS, best to survey shallow and wide • WASP will find the rare bright examples of variable objects WASP

  9. WASP-South

  10. Status • WASP-N • Operated with 5 cameras for 5 months in 2004 • 2004 data reduced and available in archive • Operations with 8 cameras due to begin in April 2006 • WASP-S • Operations recently begun with 8 cameras

  11. Archive contents: August 2005 Star counts

  16. WASP Archive • Designed and built by Richard West (Leicester) • development on-going; issues of scaling and access times • documentation at http://www.wasp.le.ac.uk/archive/ • Archive use is a two stage process • Search the catalogue for objects of interest • Download and analyse light curves • Access is via command-line-driven perl scripts • use of web-protocols to be firewall compatible • Philosophy is avoid reinventing the wheel • Data served as FITS files, so compatible with existing software • Each user can use their favourite scripting language (e.g. IDL) • Expect users to share analysis tools for common tasks • Users can also share results via new database tables

  17. Archive contents: 11 Feb 2006 pl_sky.qin 6,712,926 stars

  18. Remote user Internet Archive Archive software Catalogue database tables Bulk photometry The WASP Archive • User interface via perl scripts • wcatquery – filter database tables to select objects of interest • wlcextract – download light curves for selected objects
