SYNOPSIS

       make_slc_s1a_tops xml_file tiff_file output mode dr.grd da.grd

DESCRIPTION

       This program is part of GMTSAR.

       xml_file
              - name of xml file

       tiff_file
              - name of tiff file

       output - stem name of output files .PRM, .LED, .SLC

       mode   - (0) no SLC; (1) center SLC; (2) high SLCH and lowSLCL; (3) output ramp phase

       dr.grd - range shift table to be read in

       da.grd - azimuth shift table to be read in

       Example:    make_slc_s1a_tops    s1a-s1-slc-vv-20140807.xml    s1a-s1-slc-vv-20140807.tiff
       S1A20140807 1 dr.grd da.grd

              make_slc_s1a_tops      s1a-s1-slc-vv-20140807.xml       s1a-s1-slc-vv-20140807.tiff
              S1A20140807 1

       Output: mode 1: S1A20140807.PRM S1A20140807.LED S1A20140807.SLC

              mode   2:   S1A20140807.PRM   S1A20140807.LED   S1A20140807.SLCH   S1A20140807.SLCL
              S1A20140807.BB

       Note: if dr and da are not given, SLCs will be written with no shifts.

              s1a-aux.xml and manifest.safe(exclude the first line) should be concatenated to the
              xml_file for

              acquisitions  acquired before Mar 2015 (IPF version change). If not concatenated or
              IPF version is 2.43+,

              elevation antenna pattern correction(EAP) will not be applied

       Usage: make_slc_s1a_tops xml_file tiff_file output mode dr.grd da.grd

       xml_file
              - name of xml file

       tiff_file
              - name of tiff file

       output - stem name of output files .PRM, .LED, .SLC

       mode   - (0) no SLC; (1) center SLC; (2) high SLCH and lowSLCL; (3) output ramp phase

       dr.grd - range shift table to be read in
