Declares which child group contains a path leading to a NXdata group.

It is recommended (as of NIAC2014) to use this attribute to help define the path to the default dataset to be plotted. See https://www.nexusformat.org/2014_How_to_find_default_data.html for a summary of the discussion.

type: (optional) NX_CHARAny of these values:

`coil`

|`current-sheet`

flip_turns: (optional) NX_FLOAT {units=NX_PER_LENGTH}Linear density of turns (such as number of turns/cm) in flipping field coils

comp_turns: (optional) NX_FLOAT {units=NX_PER_LENGTH}Linear density of turns (such as number of turns/cm) in compensating field coils

guide_turns: (optional) NX_FLOAT {units=NX_PER_LENGTH}Linear density of turns (such as number of turns/cm) in guide field coils

flip_current: (optional) NX_FLOAT {units=NX_CURRENT}Flipping field coil current in “on” state”

comp_current: (optional) NX_FLOAT {units=NX_CURRENT}Compensating field coil current in “on” state”

guide_current: (optional) NX_FLOAT {units=NX_CURRENT}Guide field coil current in “on” state

thickness: (optional) NX_FLOAT {units=NX_LENGTH}thickness along path of neutron travel

depends_on: (optional) NX_CHAR

TRANSFORMATIONS: (optional) NXtransformations## This is the group recommended for holding the chain of translation ...

This is the group recommended for holding the chain of translation and rotation operations necessary to position the component within the instrument. The dependency chain may however traverse similar groups in other component groups.
