Horizontal and vertical components from IPTA outputs

Hi Sir Charles and other users,

I have implemented IPTA to get some very good results (subsidence) from ascending and descending orbits. I want to use these IPTA outputs containing average and time series deformation histories along each point targets to decompose them for horizontal and vertical components. Is there any tool/function/command available (based on the pts) for such decomposition (from IPTA output)?

Regards,
Naeem
