Panasonic RAW/RW2, also known as Leica RAW or RWL, is a raw image format used by some Panasonic and Leica digital cameras. It can also be known by a camera-specific name such as Lumix RAW or Panasonic LX3 RAW.
Different cameras produce different versions of it, and at some point the .raw file extension was changed to .rw2. The term Panasonic RAW might refer to just the .raw files, but more likely includes both .raw and .rw2.
