LAMBDA documentation

This is the documentation for LAMBDA package in version 2025.050#ed80f9d for seismic and infrasound array processing in SeisComP.

lambda allows configuring arrays interactively and during runtime. Quality parameters are visualized.

lambda provides GUIs with fully interactive data vizualisation, selection and phase picking.

PMCC, FK, backprojection and beampacking can be applied in sliding time windows to long data series.

3C particle motion analysis adds arrival time, backazimuth and slowness also for single stations outside of arrays.
