computeElevationCorrectionFromApparentElevation

double computeElevationCorrectionFromApparentElevation(AbsoluteDate date,
                                                       double apparentElevation,
                                                       double distance)

Compute the angular correction from the apparent elevation and distance.

This method takes into account the finite distance of the observed object to add a parallax correction.

Parameters:

date - The date at which we want to compute the angular correction

apparentElevation - The apparent elevation (with atmosphere) [rad]

distance - The distance to the object [m]. Can be Double.POSITIVE_INFINITY (equivalent to not take into account the parallax correction)

Returns:

the elevation correction [rad] so that apparent_elevation = geometric_elevation + elevation_correction

computeElevationCorrectionFromGeometricElevation

double computeElevationCorrectionFromGeometricElevation(AbsoluteDate date,
                                                        double geometricElevation,
                                                        double distance)

Compute the angular correction from the geometric elevation and distance.

This method takes into account the finite distance of the observed object to add a parallax correction.

Parameters:

date - The date at which we want to compute the angular correction

geometricElevation - The geometric elevation (without atmosphere) [rad]

distance - The distance to the object [m]. Can be Double.POSITIVE_INFINITY (equivalent to not take into account the parallax correction)

Returns:

the elevation correction [rad] so that apparent_elevation = geometric_elevation + elevation_correction

computeElevationCorrectionFromApparentElevation

default double computeElevationCorrectionFromApparentElevation(AbsoluteDate date,
                                                               double apparentElevation)

Compute the angular correction from the apparent elevation.

Specified by:

computeElevationCorrectionFromApparentElevation in interface AngularCorrection

Parameters:

date - The date at which we want to compute the angular correction

apparentElevation - The apparent elevation (with atmosphere) [rad]

Returns:

the elevation correction [rad] so that apparent_elevation = geometric_elevation + elevation_correction

computeElevationCorrectionFromGeometricElevation

default double computeElevationCorrectionFromGeometricElevation(AbsoluteDate date,
                                                                double geometricElevation)

Compute the angular correction from the geometric elevation.

Specified by:

computeElevationCorrectionFromGeometricElevation in interface AngularCorrection

Parameters:

date - The date at which we want to compute the angular correction

geometricElevation - The geometric elevation (without atmosphere) [rad]

Returns:

the elevation correction [rad] so that apparent_elevation = geometric_elevation + elevation_correction
