From 9158c7c55a13921b84a611570422ff14ccc8f430 Mon Sep 17 00:00:00 2001 From: Ryan Malloy Date: Mon, 23 Feb 2026 14:07:39 -0700 Subject: [PATCH 1/4] Add v0.11.0: make_orbital_elements constructors + moon equatorial functions 6 new SQL functions (114 -> 120): - make_orbital_elements(): construct from 9 floats, angles in radians - make_orbital_elements_deg(): same with angles in degrees, matches text I/O convention and typical catalog column layouts - galilean_equatorial(): geocentric RA/Dec for Io/Europa/Ganymede/Callisto - saturn_moon_equatorial(): geocentric RA/Dec for Mimas through Hyperion - uranus_moon_equatorial(): geocentric RA/Dec for Miranda through Oberon - mars_moon_equatorial(): geocentric RA/Dec for Phobos/Deimos Constructors requested by astrolock-api to replace fragile format(9 args)::orbital_elements cast pattern. Moon equatorial functions fill the last NULL RA/Dec gaps in their unified sky query. All 20 regression suites pass. --- Makefile | 5 +- ...005-pg-orrery-v011-constructors-moon-eq.md | 143 ++ pg_orrery.control | 2 +- sql/pg_orrery--0.10.0--0.11.0.sql | 51 + sql/pg_orrery--0.11.0.sql | 1390 +++++++++++++++++ src/moon_funcs.c | 167 +- src/orbital_elements_type.c | 97 ++ test/expected/v011_features.out | 224 +++ test/sql/v011_features.sql | 181 +++ 9 files changed, 2255 insertions(+), 5 deletions(-) create mode 100644 docs/agent-threads/v090-astrolock-upgrade/005-pg-orrery-v011-constructors-moon-eq.md create mode 100644 sql/pg_orrery--0.10.0--0.11.0.sql create mode 100644 sql/pg_orrery--0.11.0.sql create mode 100644 test/expected/v011_features.out create mode 100644 test/sql/v011_features.sql diff --git a/Makefile b/Makefile index 8d645e9..bf6531a 100644 --- a/Makefile +++ b/Makefile @@ -8,7 +8,8 @@ DATA = sql/pg_orrery--0.1.0.sql sql/pg_orrery--0.2.0.sql sql/pg_orrery--0.1.0--0 sql/pg_orrery--0.7.0.sql sql/pg_orrery--0.6.0--0.7.0.sql \ sql/pg_orrery--0.8.0.sql sql/pg_orrery--0.7.0--0.8.0.sql \ sql/pg_orrery--0.9.0.sql sql/pg_orrery--0.8.0--0.9.0.sql \ - sql/pg_orrery--0.10.0.sql sql/pg_orrery--0.9.0--0.10.0.sql + sql/pg_orrery--0.10.0.sql sql/pg_orrery--0.9.0--0.10.0.sql \ + sql/pg_orrery--0.11.0.sql sql/pg_orrery--0.10.0--0.11.0.sql # Our extension C sources OBJS = src/pg_orrery.o src/tle_type.o src/eci_type.o src/observer_type.o \ @@ -40,7 +41,7 @@ OBJS += $(SGP4_OBJS) REGRESS = tle_parse sgp4_propagate coord_transforms pass_prediction gist_index convenience \ star_observe kepler_comet planet_observe moon_observe lambert_transfer \ de_ephemeris od_fit spgist_tle orbital_elements equatorial refraction \ - aberration vallado_518 + aberration v011_features vallado_518 REGRESS_OPTS = --inputdir=test # Pure C — no C++ runtime needed.

All existing functions unchanged. + +## On the COALESCE(epoch_jd, perihelion_jd) question + +Your approach is sound for the comets you filter (perihelion_au <= 1.5, perihelion_year ± 1 year). Here's why: + +For near-parabolic comets (e ~ 1.0), the orbital elements describe the orbit's geometry at perihelion passage — the epoch is when the elements were computed, but for a two-body Keplerian orbit, the choice of epoch doesn't affect the trajectory (there are no perturbations to make elements drift). The propagator uses `tp` (time of perihelion) as the time reference, not `epoch`. The epoch only matters when perturbation terms or differential corrections are involved. + +Where it would break: an asteroid with `e = 0.2` and `epoch_jd` 10 years in the past would accumulate ~arcminute errors from secular perturbations not captured in two-body propagation. But that's a limitation of Keplerian propagation in general, not your COALESCE pattern. + +Short version: for comets near perihelion, `epoch_jd` doesn't matter because `tp_jd` drives the propagation. Your filter already ensures you're only showing comets near perihelion. + +## On the Python vs SQL proximity approach + +Good bridge design. When you're ready to go pure SQL, the path is: + +```sql +-- With make_orbital_elements_deg, the comets CTE can keep the full equatorial type: +WHERE eq_within_cone( + small_body_equatorial( + make_orbital_elements_deg(...), NOW() + ), + planet_equatorial_apparent(5, NOW()), + 15.0 -- radius in degrees +) +``` + +No index support yet (equatorial GiST is on the roadmap for v0.12.0), but `eq_within_cone()` runs at 1.43M/sec so sequential scan is fine for catalogs under ~100K objects. + +--- + +**Next steps for recipient:** +- [ ] Pull `main` and upgrade to v0.10.0 (tagged, ready now) +- [ ] Test v0.11.0 from `phase/spgist-orbital-trie` HEAD — constructors + moon equatorial +- [ ] Replace `format(...)::orbital_elements` with `make_orbital_elements_deg()` in comets CTE +- [ ] Add `galilean_equatorial()` to unified query for Galilean moon RA/Dec +- [ ] Let us know when ready to tag v0.11.0 diff --git a/pg_orrery.control b/pg_orrery.control index e02bf7f..e9972b3 100644 --- a/pg_orrery.control +++ b/pg_orrery.control @@ -1,4 +1,4 @@ comment = 'A database orrery — celestial mechanics types and functions for PostgreSQL' -default_version = '0.10.0' +default_version = '0.11.0' module_pathname = '$libdir/pg_orrery' relocatable = true diff --git a/sql/pg_orrery--0.10.0--0.11.0.sql b/sql/pg_orrery--0.10.0--0.11.0.sql new file mode 100644 index 0000000..9d006da --- /dev/null +++ b/sql/pg_orrery--0.10.0--0.11.0.sql @@ -0,0 +1,51 @@ +-- pg_orrery 0.10.0 -> 0.11.0 migration +-- +-- Adds make_orbital_elements() constructors and +-- geocentric equatorial functions for planetary moons. + +-- ============================================================ +-- orbital_elements constructors +-- ============================================================ + +CREATE FUNCTION make_orbital_elements( + epoch_jd float8, q_au float8, e float8, + inc_rad float8, omega_rad float8, node_rad float8, + tp_jd float8, h_mag float8, g_slope float8 +) RETURNS orbital_elements + AS 'MODULE_PATHNAME' LANGUAGE C IMMUTABLE STRICT PARALLEL SAFE; +COMMENT ON FUNCTION make_orbital_elements(float8,float8,float8,float8,float8,float8,float8,float8,float8) IS + 'Construct orbital_elements from 9 floats (angular elements in radians).'; + +CREATE FUNCTION make_orbital_elements_deg( + epoch_jd float8, q_au float8, e float8, + inc_deg float8, omega_deg float8, node_deg float8, + tp_jd float8, h_mag float8, g_slope float8 +) RETURNS orbital_elements + AS 'MODULE_PATHNAME' LANGUAGE C IMMUTABLE STRICT PARALLEL SAFE; +COMMENT ON FUNCTION make_orbital_elements_deg(float8,float8,float8,float8,float8,float8,float8,float8,float8) IS + 'Construct orbital_elements from 9 floats (angular elements in degrees).

Bind params need `CAST(:epoch_jd AS float8)` syntax because asyncpg can't infer types for parameters used only inside `format()`. + +### Three issues hit during integration + +1. **`epoch_jd` is NULL for all 1016 comets.** The MPC data ingestion populates `perihelion_jd` but not `epoch_jd`. The `orbital_elements` type requires epoch as field 1. We used `COALESCE(co.epoch_jd, co.perihelion_jd)` — for near-parabolic comets (e ~ 1.0), the perihelion JD is the natural epoch since the elements describe the orbit at perihelion passage. This works correctly for the comets we filter (perihelion_au <= 1.5, perihelion_year +/- 1 year). + +2. **PostgreSQL JOIN syntax.** Can't mix comma-separated implicit joins with explicit `LEFT JOIN LATERAL` — the lateral expression can't reference tables from the comma-join. We initially tried `LEFT JOIN LATERAL ... ON co.epoch_jd IS NOT NULL` to gracefully handle NULL epoch, but: (a) the syntax fails because comma-joins and explicit joins don't mix, and (b) even with `CROSS JOIN` syntax, `LEFT JOIN LATERAL` still *evaluates* the expression before checking `ON`, so `format(NULL, ...)::orbital_elements` fails before the guard can suppress it. + +3. **asyncpg parameter type inference.** Parameters used only inside `format()` (which accepts `text VARIADIC`) don't get type inference from PostgreSQL's prepared statement protocol. Fix: `CAST(:param AS float8)` for `epoch_jd`, `g`, `k`. + +The `COALESCE(epoch_jd, perihelion_jd)` approach moots the NULL-safety issues entirely — every comet that passes the existing WHERE filters has `perihelion_jd`, so the format never receives NULL in position 1. + +### Verification + +``` +curl /api/sky/up?min_alt=0 + -> 34 comets visible, all with non-null RA/Dec: + 306P/LINEAR: RA=6.1152h Dec=23.6166 + 197P/LINEAR: RA=14.0318h Dec=-12.5882 + P/1999 RO28: RA=3.8867h Dec=20.4029 + +curl /api/targets/comet/840/position + -> 306P/LINEAR: RA=6.1132h Dec=23.6169 Alt=82.9 Az=156.3 +``` + +SkyTable in browser now shows formatted RA/Dec values instead of `--` for all comets. + +Also added `AND co.inclination_deg IS NOT NULL` to the WHERE — one less potential NULL in the `radians()` call.

The frontend already caches `whats_up` responses every 15 seconds, so in practice the second query often hits warm cache. + +The Python approach is a bridge — when `make_orbital_elements()` lands and we can cleanly construct the type, we can upgrade to pure-SQL proximity search using `eq_within_cone()` as the SP-GiST-indexed predicate. + +### Verification + +``` +curl '/api/sky/near?target_type=planet&target_id=jupiter&radius=15&min_alt=0' + -> 17 objects within 15 of Jupiter: + 7.67 - STARLINK-5763 (satellite) + 8.33 - 217P/LINEAR (comet) <-- comet! has RA/Dec now + 8.39 - ATLAS 5 CENTAUR R/B (satellite) + 9.97 - Pollux (star) + +curl '/api/sky/near?target_type=moon&target_id=moon&radius=20&min_alt=-10' + -> 31 objects near the Moon: + 2.15 - FALCON 9 R/B (satellite) + 2.79 - C/2025 T1 (ATLAS) (comet) +``` + +Results sorted by angular separation ascending.
