GAMMA Questions

Dear Gamma users,

I want to display a deformation time series in Google Earth. After determining the linear LOS deformation rate and calculate the coherence I also generated an ascii file with disp_prt. My problem is that the LOS displacement values (written into the kml file) are not the same if I compare them with the vu_disp command (LOS rate from kml and slope from vu_disp differ - see attached png). Could you help me please where did I make a mistake?
The following commands are executed:

#generate deformation rate
def_mod_pt pt - pSLC_par - itab_ts pbase_ts 0 pdiff_ts_Ba 0 $REF_POINT pres_B pdh_B pdef_B punw_B psigma_B pmask_B 60. -0.2 0.2 5.0 5 pdh_err_B pdef_err_B
#display result
