Henry is an educational astrometry utility for
performing calculations based on a
Hertzsprung-Russel (H-R) diagram, such as
spectroscopic parallax for working out the
distance to a given star. Unlike many other
solutions that use in-built images for their H-R
diagrams, Henry plots data directly from the
European Space Agency's HIPPARCOS catalog,
allowing increased accuracy while also giving
students greater room to experiment by exploring
the catalogue themselves.

Changes:
Custom stars are now fully supported, as they were
in the C# branch, with improvements in user
interface and additional formulae added. Multiple
windows can be opened simultaneously for
comparisons, improvements have been made to color
handling in plots, usability in queries, and
plotting speed has been improved slightly. Bugs
with color changing and custom stars have been
closed.
