class_docstr: A single-band dataset resembling a Green (0.55 µm) band.
  
  This compositor creates a single band product by combining three
  other bands in various amounts. The general formula with
  dependencies (d) and fractions (f) is::
  
      result = d1 * f1 + d2 * f2 + d3 * f3
  
  See the `fractions` keyword argument for more information.
  Common used fractions for ABI data with C01, C02, and C03 inputs include:
  
  - SatPy default (historical): (0.465, 0.465, 0.07)
  - `CIMSS (Kaba) <https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2018EA000379>`_: (0.45, 0.45, 0.10)
  - `EDC <http://edc.occ-data.org/goes16/python/>`_: (0.45706946, 0.48358168, 0.06038137)
