Inverting for geodetic slip rate from InSAR profile data

[Elcappo2019]

I am currently utilizing a Jupyter notebook provided by the 'ISCE_UNAVCO_course' for the inversion of geodetic slip rates derived from InSAR profile data. I have encountered difficulties in obtaining the necessary files for running , the files are ( maksed_ll.grd , azimuthAngle_ll.grd and IncidenceAngle_ll.grd) . Attached are screenshots depicting: 1) the Jupyter notebook,

and 2) the folders associated with the ISCE InSAR processing scheme.
