SpicePosition Other Functionality

What is this document?

This is the companion to the core SpicePosition requirements document. This document contains every public method that is not mentioned in the other document. This will be an evolving document where we can collect what each method does, where it is used, and why it is used.

Methods

Time Bias

• SetTimeBias(double timeBias)
  • Used by MocNarrowAngleCamera and MocWideAngleCamera
  • NOT used. There is a function with this name used from SpiceRotation, but SpicePosition's is not used.
• GetTimeBias() const
  • Only used within SpicePosition! We could potentially eliminate this from the API, as it is only used within SpicePosition.

LightTime and Aberration Correction

• SetAberrationCorrection(const QString &correction)
  • Used by SpacecraftPosition, Spice, gllssical/main, LoHighCamera, LoMediumCamera, Mariner10Camera
• QString GetAberrationCorrection()
  • Not used anywhere (SpacecraftPosition has something similar and should probably use it but doesn't)
• GetLightTime()
  • Not used anywhere (SpacecraftPosition has something similar and should probably use it but doesn't)

GetCenterCoordinate

• GetCenterCoordinate()
  • Used by BundleObservation

HasVelocity

• HasVelocity()
  • Only used within SpicePosition

IsCached

• IsCached()
  • Used by Spice

SetPolynomialDegree

• SetPolynomialDegree(int degree)
  • Used by BundleObservation

GetSource

• GetSource()
  • Used by Spice

Base Time and Time Scaling

• ComputeBaseTime()
  • Only used within SpicePosition
• GetBaseTime()
  • Used in BundleObservation
• SetOverrideBaseTime(double baseTime, double timeScale)
  • Used in BundleObservation
• GetTimeScale()
  • Used in BundleObservation

DPolynomial

• DPolynomial(const int coeffIndex)
  • Only used within SpicePosition

Extrapolate

• Extrapolate(double timeEt)
  • Used in SpkSegment

HermiteCoordinate()

• HermiteCoordinate
  • Not used
