Based on version 2.0.1 of the UltracoolSheet.

• The ultracool package contains 3600 single ultra-cool dwarfs, 134 binary and 3 triple systems.
• The ultracool_nobins package contains 3336 objects. It is meant to be compatible with Sirius_Alpha's binary/multiple star catalog add-on (which also includes a general catalog of stars within 10 pc). Some duplicates may remain, however.
