paraview.simple.ANLSubhaloFinder(*input, **params)¶This filter assumes input similar to the output of the ANL Halo Finder’s first output port. It runs the CosmoTools subhalo finder on specified halos to determine significant subclumps of particles.
- AlphaFactor
- A tuning parameter of subhalo finding. This controls how aggressively small suhalos will be grown. Alpha factor of 1.0 is the least agrressive.
- BetaFactor
- A tuning parameter of subhalo finding. This controls how saddle points between subhalos are treated. Larger values allow identification of smaller scale structures such as tails.
- Boxsize
- The box side length used to wrap particles around if they exceed rL (or less than 0) in any dimension (only positive positions are allowed in the input, or they are wrapped around).
- HalosToProcess
- This list of halo ids which will be processed (if they exist in the data) by the filter when in ‘Only Specified Halos’ mode.
- Input
- This property specifies the input of the filter.
- Linkinglength
- Linking length measured in units of interparticle spacing and is dimensionless. Used to link particles into halos for the friends-of-friends (FOF) algorithm.
- MinimumSubhaloSize
- A subhalo candidate must have at least this many particles to be a subhalo.
- Mode
- This property specifies which halos the filter will process. When ‘All Halos’ is selected, all input halos will be processed. When ‘Only Halos Larger Than Threshold’ is selected, only halos with more than SizeThreshold particles will be processed. When ‘Only Specified Halos’ is selected, the halos whose ids are in the HalosToProcess list will be used.
- NumberofNeighbors
- The nearest X particles will be used to determine the local density in the subhalo finder where X is the value of this parameter.
- Overlap
- The space (in rL units) to extend processor particle ownership for ghost particles/cells. Needed for correct halo calculation when halos cross processor boundaries in parallel computation. Called DeadSize in the hacc config files.
- ParticleMass
- The mass of each particle.
- SPHNeighbors
- A parameter of the subhalo finder.
- SizeThreshold
- This is the minimum size of a halo that will be processed if the filter is in ‘Halos Larger Than Threshold’ mode.
- CellData
- Returns cell data information
- FieldData
- Returns field data information
- PointData
- Returns point data information
- __dict__
- dictionary for instance variables (if defined)
- __weakref__
- list of weak references to the object (if defined)
Initialize = aInitialize(self, connection=None, update=True)
- FileNameChanged(self)
- Called when the filename of a source proxy is changed.
- GetCellDataInformation(self)
- Returns the associated cell data information.
- GetDataInformation(self, idx=None)
- This method returns a DataInformation wrapper around a vtkPVDataInformation
- GetFieldDataInformation(self)
- Returns the associated cell data information.
- GetPointDataInformation(self)
- Returns the associated point data information.
- UpdatePipeline(self, time=None)
- This method updates the server-side VTK pipeline and the associated data information. Make sure to update a source to validate the output meta-data.
- UpdatePipelineInformation(self)
- This method updates the meta-data of the server-side VTK pipeline and the associated information properties
- __getitem__(self, idx)
- Given a slice, int or string, returns the corresponding output port
- GetProperty(self, name)
- Given a property name, returns the property object.
- GetPropertyValue(self, name)
- Returns a scalar for properties with 1 elements, the property itself for vectors.
- InitializeFromProxy(self, aProxy, update=True)
- Constructor. Assigns proxy to self.SMProxy, updates the server object as well as register the proxy in _pyproxies dictionary.
- ListProperties(self)
- Returns a list of all property names on this proxy.
- SetPropertyWithName(self, pname, arg)
- Generic method for setting the value of a property.
- __del__(self)
- Destructor. Cleans up all observers as well as remove the proxy from the _pyproxies dictionary
- __eq__(self, other)
- Returns true if the underlying SMProxies are the same.
- __getattr__(self, name)
- With the exception of a few overloaded methods, returns the SMProxy method
- __hash__(self)
- Return hash(self).
- __init__(self, **args)
- Default constructor. It can be used to initialize properties by passing keyword arguments where the key is the name of the property. In addition registrationGroup and registrationName (optional) can be specified (as keyword arguments) to automatically register the proxy with the proxy manager.
- __iter__(self)
- Creates an iterator for the properties.
- __ne__(self, other)
- Returns false if the underlying SMProxies are the same.
- __setattr__(self, name, value)
- Implement setattr(self, name, value).
