data

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
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
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
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)
