Phase 2 Proposal Instructions for Cycle 10

4.3 Target Description [Description]

The target description is used to sort the solar system targets by class and will be useful to archival researchers. The first word in any target description must be one of the keywords listed below. The keyword is then followed with text that depends on the target class as described below.
Table 4.2: Target Description Keywords

Keyword Description

PLANET If the target is the center of a planet, enter PLANET followed by the name of the planet (e.g., PLANET JUPITER, PLANET SATURN).

SATELLITE If the target is the center of the satellite of a planet, enter SATELLITE followed by the satellite name (e.g., SATELLITE GANYMEDE, SATELLITE 1980S27)

COMET If the target is the nucleus of a comet, enter COMET followed by its common name or catalog designation (e.g., COMET HALLEY, COMET 1979X)

ASTEROID If the target is the center of an asteroid, enter ASTEROID followed by its common name or its catalog number (e.g., ASTEROID CERES, ASTEROID 452)

FEATURE If the target is a surface feature, enter FEATURE followed by the name of the parent body (e.g., FEATURE JUPITER, FEATURE IO)

OFFSET If the target is an offset position with respect to a solar system body (but not a feature on its surface), enter OFFSET followed by the name of the parent (reference) object (e.g., OFFSET COMET HALLEY, OFFSET JUPITER)

RING If the target is in a ring, enter RING followed by the name of the parent object (e.g., RING JUPITER, RING SATURN)

TORUS If the target is a plasma torus, enter TORUS followed by the name of the parent object (e.g., TORUS JUPITER)

OTHER If your target cannot be classified under any of the categories above, then enter OTHER followed by some description of the type of observation planned (e.g., ASTROMETRIC REFERENCE, INTERPLANETARY MEDIUM, ZODIACAL LIGHT)
