What I get from the pull request is a list of friends with the following information:
"<user_id>":{ "lat":1481207023, "p":2, "vc":10 }

someone knows what the fields "p" and "vc" stand for?

[shymega]

I get this too. I think the p field might be a code that maps to an online/invisible/messengerOnline/webOnline status.

I think the p field is if they are online, when someone has just gone offline it changed to 0.
0 = offline
2 = online

The vc field appears to match more to the client. I have noticed the following numbers in the vc field.
0 = Always matches p with zero so client/user just gone offline
10 = ?
8 = ?
74 = Always seen this when user is using facebook app on mobile I think.
