I'm looking at this table right now = https://community.nxp.com/t5/Sensors/freescale-9-axis-sensor-fusion-specification/m-p/1165124#M6316
I get a 13 degree sensor output on a 13.7 degree surface. It says there is an ancestor of 0.05 degrees per degree according to this table
Is the accelerometer alignment error in the table per degree ? I hope I'm not wrong
