Outer Sunset... or Parkside?

Hi folks, especially those in the Sunset and Parkside neighborhoods! What are the official neighborhood boundaries for the Outer Sunset and Parkside neighborhoods? I always thought the north and south boundaries for the Outer Sunset were Lincoln and Sloat respectively, but I've learned that Parkside is in there somewhere along Sloat. I've seen maps that show that the Outer Sunset occupies the area bordering Ocean Beach to the west and Sloat to the south--and that's how Wikipedia defines it. But I also see maps that show Parkside occupies the southern section of the Sunset neighborhood from the beach up to around 15th Ave/Funston--and some of these maps show an Outer and Inner Parkside. I ask because I recently moved to the Outer Sunset. I live firmly in the Outer Sunset (on Judah near the beach), but I want to know what the majority of folks consider to be the neighborhood boundaries. On a related note, I've never heard anyone say they live in the Central Sunset, but apparently that exists, too? Thanks!
