GPT graph processing differs from SNAP's

Thanks for yout help, @gnwiii and @mengdahl. My advisor could find this issue here that led us to a solution. Thankfully GPT is working fine, and our graph was actually incorrect.

In the graph XML, the multilook nRgLooks (number of range looks) tag was set to 1 (<nRgLooks>1</nRgLooks>) by default. In SNAP though, this setting it is automatically set to 4 in this kind of input data. So we changed it accordingly in our XML, and now the output comes as expected.

  <node id="Multilook">
    <operator>Multilook</operator>
    <sources>
      <sourceProduct refid="TOPSAR-Deburst"/>
    </sources>
    <parameters class="com.bc.ceres.binding.dom.XppDomElement">
      <sourceBands/>
      <nRgLooks>4</nRgLooks>
      <nAzLooks>1</nAzLooks>
      <outputIntensity>false</outputIntensity>
      <grSquarePixel>true</grSquarePixel>
    </parameters>
  </node>
