 insar: users should be mostly interested in this folder. For the explanations of the files, please refer
 to the xml files in folder "explanations". You can find the differential interferograms without and with
 ionospheric correction if you have chosen to do ionospheric correction. For example,

 "upper", and final computations are done in "ion_cal".
