Reach RS2 Data Collection

I set position output to Serial with the device USB-to-PC. I then monitored the COM port my RS2 was connected to and logged the data being generated. What I got looked like this:

The first 5 entries are date, time, latitude, longitude, and height. I need to know what the remaining 10 entries correspond to. Does anyone know?

I get up to the number of satellites (for my data being 7 on the last entry). Can you explain the remaining entries?

Sigmas in i direction:
-North
-East
-up
-North-East
-East-Up
-Up-North
-Age of Differential
-AR validation ratio (Pre RS2)
