about avgPhaseVelocity.h5

Hi MintPy/InSAR community

I am exploring a stacking approach in MintPy (using avgPhaseVelocity.h5) to map anomalous deforming areas. I decided to move from time‐series InSAR analysis to a stacking method because unwrapping errors tend to propagate through the time series and contaminate the results.

I understand that unreliable interferograms can be excluded by applying a coherence threshold in the configuration file. However, I would also like to implement a pixel-based masking strategy so that only unreliable pixels are removed, rather than discarding entire interferograms. This could potentially be done using a coherence mask or connected-component layers.

Are there recommended tools or workflows in MintPy (or related software) that support pixel-level quality control for stacking? Alternatively, are there other methods that could improve the robustness of stacking-based deformation mapping?

Best Regards,
