Hi @zerafachris, just to avoid misanderstanding in case someone reads this post: No seismic signal present around the EGO site have been released to the public and I don’t foresee a release in the near future. Even if they would be released the channel names would be different since we are talking of another detector.
I think “IFO” basis refers to a coordinate axes aligned with the instrument. So - the X-axis would point in the direction of the X-arm, the Y-axis would point in the direction of the Y-arm, and the Z-axis would point up.
LVEA: Laser and Vacuum Equipment Area (at observatory corner station)
IFO: Interferometer
The “IFO basis” is a (x, y, z) coordinate system where the x and y axes are the x and y arms of the interferometer, respectively. This allows you to figure out which direction of motion the seismometer is measuring.
