Type Members

1.  trait EphemerisCompression extends AnyRef

   FS2 pipes for discarding ephemeris elements that differ one from the other by less than a given Δ velocity or accumulated acceleration.

2.  final case class EphemerisContext(key: Horizons, site: Site, meta: Option[EphemerisMeta], rnge: Option[(Timestamp, Timestamp)], soln: Option[HorizonsSolutionRef]) extends Product with Serializable

   Collection of information related to an ephemeris.

   Collection of information related to an ephemeris. Used to determine whether an update is needed.

   key

   unique horizons id of the object

   site

   information valid for the given site

   meta

   associated ephemeris metadata, if any

   rnge

   earliest and latest ephemeris element times, if any

   soln

   current horizons solution reference from JPL, if any

3.  sealed trait HorizonsEphemerisQuery extends AnyRef

   Representation of an Horizons ephemeris query.

4.  final case class HorizonsEphemerisUpdater[M[_]](xa: doobie.Transactor[M])(implicit evidence$1: LiftIO[M], bracket: Bracket[M, Throwable]) extends Product with Serializable

   Utility for inserting / updating en ephemeris.

5.  sealed trait HorizonsNameQuery[A] extends AnyRef

   Horizons name-resolution query.

   Horizons name-resolution query.

   import HorizonsNameQuery.Search.Comet
   
   HorizonsNameQuery(Comet("Halley")).lookup.value.unsafeRunSync

6.  sealed trait HorizonsSolutionRefQuery extends AnyRef

   Horizons solution reference query.

   Horizons solution reference query. Horizons supports a version number, of sorts, for comet and asteriod ephemeris calculations. The version is an opaque String that can be used to compare for equality against previous versions to determine if an update is required. Unfortunately, major bodies do not include solution references.

   import gem.EphemerisKey
   import gem.horizons.HorizonsSolutionRefQuery
   
   HorizonsSolutionRefQuery(EphemerisKey.Comet("81P")).lookup.unsafeRunSync
