    • loadData

      public List<IParticleRecord> loadData​(String file, double factor)
      Description copied from interface: IStarGroupDataProvider
      Loads the data applying a factor.
      Parameters:
      file - The file to load
      factor - Factor to apply to the positions
      Returns:
      Array of particle beans

    • loadData

      public List<IParticleRecord> loadData​(uk.ac.starlink.util.DataSource ds, double factor)

    • loadData

      public List<IParticleRecord> loadData​(uk.ac.starlink.util.DataSource ds, double factor, Runnable preCallback, RunnableLongLong updateCallback, Runnable postCallback)
      Parameters:
      ds - The data source.
      factor - Length factor.
      preCallback - A function that runs before.
      updateCallback - A function that runs after each object has loaded. Gets two longs, the first holds the current number of loaded objects and the second holds the total number of objects to load.
      postCallback - A function that runs after the data has been loaded.
      Returns:
      The list of particle records.

    • loadData

      Description copied from interface: IParticleGroupDataProvider
      Sets a cap on the number of files to load. Set to negative for unlimited
      Specified by:
      setFileNumberCap in interface IParticleGroupDataProvider
      Overrides:
      setFileNumberCap in class AbstractStarGroupDataProvider
      Parameters:

    • setParallaxErrorFactorFaint

      public void setParallaxErrorFactorFaint​(double parallaxErrorFactor)
      Description copied from interface: IStarGroupDataProvider

      The loader will only load stars for which the parallax error is at most the percentage given here, in [0..1]. This applies to faint stars (gmag >= 13.1) More specifically, the following must be met:

      pllx_err < pllx * pllxErrFactor

      setParallaxErrorFactorFaint in interface IStarGroupDataProvider
      Overrides:
      setParallaxErrorFactorFaint in class AbstractStarGroupDataProvider
      Parameters:
      parallaxErrorFactor - The percentage value of parallax errors with respect to parallax

    • setParallaxErrorFactorBright

      public void setParallaxErrorFactorBright​(double parallaxErrorFactor)
      Description copied from interface: IStarGroupDataProvider

      The loader will only load stars for which the parallax error is at most the percentage given here, in [0..1]. This applies to bright stars (gmag < 13.1) More specifically, the following must be met:

      pllx_err < pllx * pllxErrFactor
      Specified by:
      setParallaxErrorFactorBright in interface IStarGroupDataProvider
      Overrides:
