| | | | | | | | | | | | | the case of empty list of points which was designed to remove a RuntimeWarning at the first run of the code (see Ticket # 1079). For unknown reasons, this change was lost during last commit by Mike. Moved point vector-normalization from the add_node method to Node.__init__(...) in graph.py. Removed skyline.py from the 'sphere' module. The original implementation of skyline.py did not work correctly (see, e.g., tickets #1080, #1081, #1082) and overall it makes sense to separate image processing and statistical analysis from "pure" geometric operations handled by the 'sphere'. git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/branches/sphere@29976 fe389314-cf27-0410-b35b-8c050e845b92 Former-commit-id: 82f06f5b25c8cc262bfbc0b57e3e774d320bcf47
