Hello!
I have been searching for some time documentation about parameters which are logged in dataflash logs.
For example:
In Dataflash LOG, there is section NTUN.
I am interested about VelX, VelY - min/max possible values and measurement unit - is it cm/s???
And what does it mean if my values are max 400 and -400, look at the attachment?
Only documentation, that I found is here, but no information about possible min/max values and units are not also present:

NTUN (navigation information):
| WPDst | Distance to the next waypoint (or loiter target) in cm. Only updated while in Loiter, RTL, Auto flight modes. |
| WPBrg | Bearing to the next waypoint in degrees |
| PErX | Distance to intermediate target between copter and the next waypoint in the latitude direction |
| PErY | Distance to intermediate target between copter and the next waypoint in the longitude direction |
| DVelX | Desired velocity in cm/s in the latitude direction |
| DVelY | Desired velocity in cm/s in the longitude direction |
| VelX | Actual accelerometer + gps velocity estimate in the latitude direction |
| VelY | Actual accelerometer + gps velocity estimate in the longitude direction |
| DAcX | Desired acceleration in cm/s/s in the latitude direction |
| DAcY | Desired acceleration in cm/s/s in the longitude direction |
| DRol | Desired roll angle in centi-degrees |
