 ### Example data
 
-A stack of 9 example SAR images is contained in the ```data\``` directory. The example SAR images are a set of multi-looked intensity images acquired by Sentinel-1 in Interferometric Wide Swath mode. These images have been processed from Single Look Complex data using the GAMMA Remote Sensing software with 4 Looks in range and 1 Look in azimuth.
+A stack of 9 example SAR images is contained in the ```data\``` directory. The example SAR images are a set of multi-looked Sigma-0 intensity images acquired by Sentinel-1 in Interferometric Wide Swath mode. These images have been processed from Single Look Complex data using the GAMMA Remote Sensing software with 4 Looks in range and 1 Look in azimuth.
 Each tiff file (```*.tif```) contains 200*200 floating point values. Each data file has an accompanying text file (```*.mli.par```) containing metadata generated by the GAMMA Remote Sensing software.
 The example images, in descending-pass radar geometry, cover a small area cropped from the full images containing a test site "SERF" at Samford, Queensland, Australia. A corner reflector target was deployed at SERF for teaching purposes in August 2018.
