get wrong radar_frequency using spool --load #125

Open GEOSCIENCELXG opened 1 month ago

GEOSCIENCELXG commented 1 month ago

I used the following command to load the data processed by GAMMA software, but it wrongly found the SLC parameter based on dinsar.utm.dem.par instead of SLC.par (in which the correct radar_frequency is 1.236GHz rather than the bellow one 5.405 GHz). There is no frequency information in the dinar.utm.dem.par, so the 5.405 GHz following the command seems to be the default.

kite version: 1.5.6 (I tried different version 1.5.0-8, it does not work)

the files list in the current folder is: dinsar.phi dinsar.theta
dinsar.sm2.mask.utm.unw dinsar.utm.dem.par slc.par

spool --load '/data1/DInSAR/beatformat/dinsar.sm2.mask.utm.unw'

Is the displacement amplitude correct though?
