An existing product called PG Orbit (a mobile PostgreSQL client) creates a naming conflict. pg_orrery — a database orrery built from Keplerian parameters and SQL instead of brass gears. Build system: control file, Makefile, Dockerfile, docker init script. C source: GUC prefix, PG_FUNCTION_INFO_V1 symbol, header guards, ereport prefixes, comments across ~30 files including vendored SGP4. SQL: all 5 install/migration scripts, function name pg_orrery_ephemeris_info. Tests: 9 SQL suites, 8 expected outputs, standalone DE reader test. Documentation: CLAUDE.md, README.md, DESIGN.md, Starlight site infra, 36 MDX pages, OG renderer, logo SVG, docker-compose, agent threads. All 13 regression suites pass. Docs site builds (37 pages).

The TASS 1.7 theory of the Saturnian satellites including HYPERION
|
|
by Alain VIENNE and Luc DURIEZ can be found at
|
|
ftp://ftp.imcce.fr/pub/ephem/satel/tass17
|
|
|
|
I (Johannes Gajdosik) have just taken the Fortran code and data
|
|
obtained from above and rearranged it into this piece of software.
|
|
|
|
I can neither allow nor forbid the usage of the TASS 1.7 theory.
|
|
The copyright notice below covers not the work of Alain VIENNE and Luc DURIEZ
|
|
but just my work, that is the compilation of the TASS 1.7 theory
|
|
into the software supplied in this file.
