hpmcm.match_utils module

hpmcm.match_utils.heirarchicalProcessCluster(cluster, cell_data, pixel_r2_cut)

Function that is called recursively to split clusters until they consist only of sources within the match radius of the cluster centroid.

Recursively process a cluster and make associated objects

Return type:

list[ObjectData]

Parameters:

• cluster (ClusterData) – Cluster being processed

• cell_data (CellData) – Associated cell

• pixel_r2_cut (float) – Distance cut for associated, in pixels**2

Return type:

Objects produced in cluster processing

hpmcm.match_utils.heirarchicalProcessObject(obj_data, cell_data, pixel_r2_cut, recurse=0)

Recursively process an object and make sub-objects

Return type:

None

Parameters:

• obj_data (ObjectData) – Object being processed

• cell_data (CellData) – Associated cell

• pixel_r2_cut (float) – Distance cut for associated, in pixels**2

• recurse (int) – Current recursion level

Notes

This function will test if the input obj_data is good, i.e., that all the sources lie within the pixel_r2_cut, and will split obj_data into multiple objects if some of the sources lie outside the cut

The new objects will be added to the parent cluster of the original object

hpmcm.match_utils.heirarchicalSplitObject(obj_data, cell_data, pixel_r2_cut, recurse=0)

Split up a cluster keeping only one source per input catalog

Return type:

None

Parameters:

• obj_data (ObjectData) – Object being processed

• cell_data (CellData) – Associated cell

• pixel_r2_cut (float) – Distance cut for associated, in pixels**2

• recurse (int) – Current recursion level

Notes

This function actually does the splitting of objects
