Workflow: Relative Velocity Variations

This section only presents relative veloctity computations part of the workflow, assuming the Workflow: Cross-Correlation Functions step has been done previously.

You have currently three options to compute the dv/v:

1. MWCS → dt/t → dv/v (3 steps!)

• Compute MWCS (Moving Window Cross-Spectrum)
• → Plot MWCS results
• Compute dt/t from MWCS measurements
• Compute dv/v from dt/t(MWCS)
• → Plot dv/v from dt/t(MWCS)

2. Stretching (1 step)

• Compute Stretching
• → Plot dv/v from Stretching

3. Wavelet-based dv/v (1 step)

• Compute WCT (Wavelet Coherence Transform)
• → Plot dv/v from WCT
