24 WASP: getting started Peter Wheatley p.j.wheatley@warwick.ac.uk 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 1.Search the catalogue for objects of interest 2.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 1.Data served as FITS files, so compatible with existing software 2.Each user can use their favourite scripting language (e.g. IDL) 3.Expect users to share analysis tools for common tasks 4.Users can also share results via new database tables
