loadData
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:
- The array of particle records.
-
loadData
-
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:IStarGroupDataProvider

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
- Specified by:
setParallaxErrorFactorFaint
in interfaceIStarGroupDataProvider
- Overrides:
setParallaxErrorFactorFaint
in classAbstractStarGroupDataProvider
- 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 interfaceIStarGroupDataProvider
- Overrides:
setParallaxErrorFactorBright
in classAbstractStarGroupDataProvider
- Parameters:
parallaxErrorFactor
- The percentage value of parallax errors with respect to parallax.
-
setParallaxZeroPoint
