File formats
• Raw data files (1 second duration)– fs <= 16384 Hz
• Frame files (1 minute duration)– fs <= 16384 Hz– 60 frames per file, one second per frame– All channels in one file
• Hour trends files (1 hour duration)– fs = 1 Hz– Min, max, av
• Day trend files (1 day duration)– fs = 1/60 Hz– Min, max, av
20 days of data

GEO++ and Triana
• Developed at Cardiff University
• Idea: To get a tool that can deal with a large amount of data
Software environment - GEO++– Process large number of
channels with many algorithms – Store faithful summary – Triana Tools for retrieval of
results from the database
GEO++ Monitors

Environmental sensorsInstrumental monitorsMain h(t) channel
Data Mining using Triana
Display results stored in the database

GEO++ Main Monitors
• InspiralSenseMon
• GlitchMon
• HACRMon
• LineMon
• PowerTrackerMon
• SaturationMon
• AmplitudeCouplingMon
• PhaseCouplingMon
• CoherenceMon
• BicoherenceMon
Used for ‚real‘ data analysis
Online running monitors, that can be used for
detector charaterisation
For various reasons we do not often use GEO++ / Triana for commissioning (?)

Monitors
Not ‚real‘ data tools, but can give us useful hints for commissioning
• Alarm.vi
• Vacuum.vi
• Drift.vi
• Temperature.vi

Possible data exchange (discussion)
At the moment data access for the use of commissioning seems only to be sensible, if the
commissioners are personally at the site (???)
In future maybe data access for the use of commisioning should also be possible
from a different antenna site(???)

Data access at the site
1. Use one of the computers at the site:
No problem
No problem at all• Everything is in place
2. Use of your personal computer:
• You need to install the software on your computer
• We provide all tools (matlab-files, oscilloscope.vi)
• Access to raw data and frame server
Stand alone data viewer

Stefan Hild Ilias WG1 meeting, Hannover, September 2004
Data access from outside the side (need ?)
No problem
Allow server access for your personal IP adress
• Probably only access to the hannover frame server available (due to our security philosophy no access to the raw data server in Ruthe)
But now you are outside our domain and behind several firewalls!
• Only use your personal computer (???)
• You need software
• We provide all tools (matlab-files, labview oscilloscope)
