Probably need more information that this. What element is being 'removed' from
a normal acceleration measurement? What are units after application of offset and
scale? Can cross refer to the in_accel_x_raw for that info if you like.

Also, but them immediately after the block with the in_accel_x_raw etc

The organization fo that file needs a rethink but let us try to avoid making
it worse in the meeantime!
