Main files
1- Geocoded wrapped phases from original NSBAS interferogram files (*.int) 
    geo_filtSW_<date1>-<date2>_int_rad_4rlks.tif
    File name convention:
    - geo             -> Geocoded
    - filtSW          -> Filter type. Additional filtering parameters: FilterStrength=0.8, filterstyle=SW, SWwindowsize=4
    - <date1>-<date2> -> <primary>-<secondary> image
    - int             -> NSBAS source file
    - rad             -> [Units]. Follows NSBAS sign convention, i.e, positive values represent range increase
    - 4rlks           -> Number of range looks
2- Geocoded unwrapped phases corrected for ramp and phase-correlated signals, i.e., pha = a*X + b*Y + c*DEM + d 
    geo_filtSW_<date1>-<date2>_unw_mm_4rlks.tif 
    File name convention:
    - geo             -> Geocoded
    - filtSW          -> Filter type used on the wrapped phases (same as before)
    - <date1>-<date2> -> <primary>-<secondary> image
    - unw             -> NSBAS source file. Additional unwrapping parameters: threshold_unw = .4
    - mm              -> [Units]. A factor of -4.4563 was used to convert the unwrapped and corrected phases from radians 
                         to millimeters. Positive values represent range decrease and/or upward motion
    - 4rlks           -> Number of range looks
3- Geocoded look angle 
    - geo             -> Geocoded
    - <A/D>???        -> Looking geometry, i.e, ascending (A), and descending (D), and track number (as from Alaska Satellite Facility)
    - incidence       -> NSBAS source file. Only the first band used
    - deg             -> [Units]
    - 4rlks           -> Number of range looks
 
4- KML files with the geocoded unwrapped phases corrected for ramp and phase-correlated signals
    - <A/D>s_???      -> Looking geometry, i.e., ascending (As), descending (Ds), and track number (as from Alaska Satellite Facility)
    - <date1>-<date2> -> <primary>-<secondary> image

5- PNG files
    - Rendered images of the geocoded unwrapped phases corrected for ramp and phase-correlated signals associated with the KML files
