This is to be used if there is no actuator/sensor that controls/measures the environment parameters, but the user would still like to give a value for it. An example would be a room temperature experiment where the temperature is not actively measured, but rather estimated. Note that this method for recording the environment parameters is not advised, but using NXsensor and NXactuator is strongly recommended instead. .. _/NXenvironment/depends_on-field: .. index:: depends_on (field) **depends_on**: (optional) :ref:`NX_CHAR ` .. collapse:: NeXus positions components by applying a set of translations and rotations ... NeXus positions components by applying a set of translations and rotations to apply to the component starting from 0, 0, 0. The order of these operations is critical and forms what NeXus calls a dependency chain. The depends_on field defines the path to the top most operation of the dependency chain or the string "." if located in the origin. Usually these operations are stored in a NXtransformations group. But NeXus allows them to be stored anywhere. .. _/NXenvironment/position-group: **position**: (optional) :ref:`NXgeometry` .. collapse:: The position and orientation of the apparatus. ...
