NaNs appear while GPT graph processing + writing to NetCDF4

[marcosrdac]

@marcosrdac

graph
reads an input Sentinel-1 file and then performs: radiometric calibration, applies orbit file, deburst and multilook. The output is converted to dB and saved as NetCDF4

After more research, I created a better description of the problem here.

As a correction to this post, the pixels were actually not NaNs but masked zeros.
