Appendix: Supported hosts

A host is a supported collection. Each host has its own directory under src/metadata_tools/hosts/<HOST>/ containing its configuration, its label templates, and the runnable <HOST>_index.py / <HOST>_geometry.py / <HOST>_cumulative.py programs (and their *_cloud.py counterparts).

The programs and options documented in this guide are the same for every host; only the <HOST> prefix and the host-specific defaults change. To add support for a new collection, see Extending the system.

NAIF spacecraft ID

-77

Data label glob

oops host module

oops.hosts.galileo.ssi

The host’s mission table maps spacecraft-clock ranges to the primary body and the bodies of interest for the Venus, Earth, SL9, and Jupiter phases of the mission. Calibration and similar observations are excluded by the host’s exception patterns. These details live in the host’s geometry_config.py and are described, as an extension example, in Extending the system.
