What do the various dots and triangles mean on the minimap in Titanfall and what governs their display?

Here is how I think it works:

Small red dots       - Enemy minions
Big red dots         - Enemy pilots who are firing a weapon?
Small blue triangles - Friendly pilots
Big Red Triangles    - Enemy Titans
Big Blue Triangles   - Friendly Titans
Orange dots          - Enemy minions (using minion detector?) 

So my questions are:

• Do enemy pilots only show on the mini-map when they are firing a weapon with no suppressor?
• Do friendly pilots only show on the mini-map when they are firing a weapon with no suppressor?
• Does the Map Hack burn card let you see all pilots regardless of whether or not they are firing?
• Does the Satellite Uplink burn card let you see all enemy pilots regardless of whether or not they are firing?
