ITER Physics Data Model Documentation for camera_visible

Camera in the visible light range

Notation of array of structure indices: itime indicates a time index; i1, i2, i3, ... indicate other indices with their depth in the IDS. This notation clarifies the path of a given node, but should not be used to compare indices of different nodes (they may have different meanings).

ids_properties/homogeneous_time This node must be filled (with 0, 1, or 2) for the IDS to be valid. If 1, the time of this IDS is homogeneous, i.e. the time values for this IDS are stored in the time node just below the root of this IDS. If 0, the time values are stored in the various time fields at lower levels in the tree. In the case only constant or static nodes are filled within the IDS, homogeneous_time must be set to 2 {constant} INT_0D

ids_properties/provenance/node(i1)/sources(:) List of sources used to import or calculate this node, identified as explained below. In case the node is the result of of a calculation / data processing, the source is an input to the process described in the "code" structure at the root of the IDS. The source can be an IDS (identified by a URI or a persitent identifier, see syntax in the link below) or non-IDS data imported directly from an non-IMAS database (identified by the command used to import the source, or the persistent identifier of the data source). Often data are obtained by a chain of processes, however only the last process input are recorded here.

channel(i1)/optical_element(i2)/geometry/geometry_type Type of geometry used to describe the surface of the detector or aperture (1:'outline', 2:'circular', 3:'rectangle'). In case of 'outline', the surface is described by an outline of point in a local coordinate system defined by a centre and three unit vectors X1, X2, X3. Note that there is some flexibility here and the data provider should choose the most convenient coordinate system for the object, respecting the definitions of (X1,X2,X3) indicated below. In case of 'circular', the surface is a circle defined by its centre, radius, and normal vector oriented towards the plasma X3. In case of 'rectangle', the surface is a rectangle defined by its centre, widths in the X1 and X2 directions, and normal vector oriented towards the plasma X3. {static} INT_0D
channel(i1)/optical_element(i2)/geometry/centre If geometry_type=2, coordinates of the centre of the circle. If geometry_type=1 or 3, coordinates of the origin of the local coordinate system (X1,X2,X3) describing the plane detector/aperture.
