class_docstr: A single-band dataset resembling a Red (0.64 µm) band.
  
  This compositor creates a single band product by combining two
  other bands by preset amounts. The general formula with
  dependencies (d) and fractions (f) is::
  
      result = (f1 * d1 - f2 * d2) / f3
  
  See the `fractions` keyword argument for more information.
  The default setup is to use:
  
   - f1 = 1.0
   - f2 = 0.13
   - f3 = 0.87
