One allows to extract the source positions being read, and figure out the bands (and eventually also a gutter, in case there are relative source positions)
One allows to remap the bands, so that even if the script says "read band 3" you can make the code read band "0".
The final one is just a fix in the image viewer, that was not displaying properly double/float rasters.
