 Description:
                Raw (unscaled no bias removal etc.) temperature measurement.
                If an axis is specified it generally means that the temperature
                sensor is associated with one part of a compound device (e.g.
-               a gyroscope axis). Units after application of scale and offset
+               a gyroscope axis). The ambient and object modifiers distinguish
+               between ambient (reference) and distant temperature for contact-
+               less measurements. Units after application of scale and offset
                are milli degrees Celsius.
