Cross-link discussion

  • Merge Geopsy: Tools and Menu tools
  • Copy part of 'Ambient_vibration_array#Common_pre-requisites_for_array_processing_-_getting_ready' to Geopsy: Tools and make link, merge also with spac description of the same widget.
  • Move the time limit editor description to an individual page
  • Revise and eventually move windowing param to H/V
  • Quote instead of image for command line or text file contents (in FK and SPAC)
  • Curve browser: expand parser description and move some descriptions from Curve Browser
  • How FFT are computed in Geopsy
  • Use of console: revert signal processing + save temporary signals
