Type Members

1.  sealed class Angle extends AnyRef

   Exact angles represented as integral microarcseconds.

   Exact angles represented as integral microarcseconds. These values form a commutative group over addition, where the inverse is reflection around the 0-180° axis. The subgroup of angles where integral microarcseconds correspond with clock microseconds (i.e., where they are evenly divisible by 15 microarcseconds) is represented by the HourAgle subtype.

   Lawful conversion to and from other types/scales is provided by optics defined on the companion object. Floating-point conversions are provided directly

   Representation of a radial velocity in meters per second Unlike RadialVelocity this is not limited to the speed of light Apparent Radial Velocity is often represented as cz

4.  final case class BrightnessValue(scaledValue: Int) extends Product with Serializable

   Exact brightness value represented as an int with the original value scaled up

   Exact brightness value represented as an int with the original value scaled up

5.  final case class Coordinates(ra: RightAscension, dec: Declination) extends Product with Serializable

6.  trait CoordinatesOptics extends AnyRef
7.  type Dec = Declination
8.  sealed abstract case class Declination extends Product with Serializable

   Celestial latitude, measured in angular distance from the celestial equator.

   Celestial latitude, measured in angular distance from the celestial equator. Points north of the celestial equator have positive declinations, while those south have negative declinations. This is a newtype wrapper for an Angle constrainted to the range [-90°, 90°], or [270 - 360) + [0 - 90] in terms of the underlying Angle. Note that the range is *inclusive* of both poles.

10.  final class Epoch extends AnyRef

    An epoch, the astronomer's equivalent of Instant, based on a fractional year in some temporal scheme (Julian or Besselian) that determines year zero and the length of a year.

    An epoch, the astronomer's equivalent of Instant, based on a fractional year in some temporal scheme (Julian or Besselian) that determines year zero and the length of a year. The only meaningful operation for an Epoch is to ask the elapsed epoch-years between it and some other point in time. We need this for proper motion corrections because velocities are measured in motion per epoch-year. The epoch year is stored internally as integral milliyears.

22.  sealed abstract case class Parallax extends Product with Serializable

    Parallax stored as microarcseconds Normally parallax is expressed in milliarcseconds but simbad reports them with a higher precision thus using microarcseconds gives us enough space.

    Parallax stored as microarcseconds Normally parallax is expressed in milliarcseconds but simbad reports them with a higher precision thus using microarcseconds gives us enough space. Parallax values need to be in the interval [0°, 180°]. 180° is a theoretical limit - actual astronomical values will be very small.

    Represents a redshift of an object as it moves away (positive) or towards (negative) the observing point

    Represents a redshift of an object as it moves away (positive) or towards (negative) the observing point

    Redshift can be (perhaps surprisingly) higher than 1.

    For far objects Redshift can be converted to RadialVelocity which takes into account relativistic effects and cannot be more than C For nearer objects we can convert to ApparentRadialVelocity which doesn't consider relativistic effects

    Often Redshift is referred as z
