Allow computation with manual specification of leaves #36

Closed low-sky closed 11 years ago

low-sky commented 11 years ago

Anticipating that the astrodendro routines will be ultimately used as the core functionality for cataloging of structures based in python, it will become important to be able to specify the indices of the leaves that will define the dendrograms. Specifically, this is necessary functionality to recompute the dendrogram after filtering and pruning.

This is replicating the functionality lost by dropping friends and specfriends from the base API. I envision a use case where the dendrogram is computed, the leaves are then filtered based on delta or minimum/maximum separation in pixel space.

I think it would be okay if this functionality can insist that these leaves are a subset of an original dendrogram leaves.

Agreed, though issues #7 and #8 cover this

So sorry. Missed that in my haste at this meeting. Closing
