 Depending on the observation type, different extraction techniques can be used to extract the relevant information from the observations. These are currently the techniques implemented:
 
-- [Observer](macq/extract.html#observer)
-- [SLAF](macq/extract.html#slaf)
-- [ARMS](macq/extract.html#arms)
-- [AMDN](macq/extract.html#amdn)
