  1. as an easy way to get GDS triggers and other data A. Di Credico Syracuse University DetCamp 04 Running GUILD

  2. What is GUILD • GUILD (Graphical User Interface to the LDAS data metabase) is a package written by P.Shawhan • It is extremely flexible and user friendly, a tool that can be efficiently used by students for basic trigger analysis, the only “limitation” being the need for an LDAS account

  3. How do we get GUILD • The absolute reference is this web-page: http://www.ldas-sw.ligo.caltech.edu/ligotools/ • Easy to install, there are version for practically all platforms : very practical on Windows systems

  4. What can we do with GUILD • Retrieve frame data (Gaby’s talk yesterday) • Retrieve GDS triggers • produced in a selected period • produced by a particular (set of) monitor(s) or channel(s) • Save triggers in different formats (ASCII, XML) • > we can analyze them with EventTool (Laura’s talk yesterday) • > we can feed them to Matlab or any other code

  5. Example – retrieve GDS triggers • Choose LDAS server : stay local • Database name : here you choose the science run/period • LDAS metadata database: choose GDS triggers • Build the query for the GDS triggers table (see real time example) • Submit the query • Save result in desired format and you’re done! • Note: the help pages are really helpful !!! • Also, try the practical tool for GPS time convertion (no need for LDAS password)
