PRS Small Bodies Facets

Here are the facets I've proposed for the "small bodies" discipline list, with definitions:

Facet1 Value	Meaning
dust studies	Dust measurements of all kinds and targets
dynamic properties	Orbital parameters, proper elements, etc.
historic references	Discovery circumstances, reference collections
lightcurves	Light intensity variation with time, including rotational, secular, and occultation light curves
meteoritics	Meteor shower counts, meteorite studies
physical properties	Mass, density, albedo, etc.
production rates	Quantification of mass loss from, e.g., the nucleus of a comet: molecule production rates, Afρ, etc.
shape models	Shape models, slope models, terrain models, elevation models, etc.
taxonomy	Physical and dynamical taxonomies of small bodies
