public class PointingModel
extends PropertyBundles
implements Initializable

Class to calculate a pointing model for STELLA and RoboTel. Its is general enough to comply with any pointing model possible, though it is only used for the STELLA pointing model:

 Δaz=c_an*sin(az)*cot(z)-c_ae*cos(az)*cot(z)+c_npae*cot(z)-c_ca/sin(z)+c_aoff
    Δz=c_an*cos(az)+c_ae*sin(az)+c_flex*sin(z)+c_zoff
 

It remains questionable, if parameters c_an c_ae are really identical for both offsets, in most of the pointing models I came across, they were different. Thus, this class uses two different parameters. Adding additinal terms or removing terms is especially easy, just add an expression to the appropriate #AZMODEL or #ALTMODEL. A second question is how the measurement get into the object. Refer to appropriate classes here, e.g. #FileData.

Note that this class can in principle also be used for finding a temperature/heigth model for the focus, if proper changes in the fitting functions and usage of the correct data set is done.

Sets the zenith distance data. As for the default model, zenith distance must be given in radians.

setZenithDistance

public void setZenithDistance(VectorG z)

Sets the zenith distance data. The zenith distance is converted into height here.

setAzimuthOffsets

public void setAzimuthOffsets(VectorG off,
                              VectorG err)

Sets the measured azimuth offsets and the erros, if available. The unit of the offset defines the unit of the fitting parameters, i.e. you can use arcminutes, degrees or radians here.

Parameters:

off - The measured offsets in azimuth.

err - Measurement errors or null.

setAzimuthEncoderOffsets

public void setAzimuthEncoderOffsets(VectorG off,
                                     VectorG err)

Sets the azimuth data. This method requires that the height data has been set before, because the azimuth is multiplied with cosine of the height.

setZenithOffsets

public void setZenithOffsets(VectorG off,
                             VectorG err)

Sets the measured zenith distance offsets and the erros, if available. The unit of the offset defines the unit of the fitting parameters, i.e. you can use arcminutes, degrees or radians here.

Parameters:

off - The measured offsets in zenith distance.

err - Measurement errors or null.

setAltitudeOffsets

public void setAltitudeOffsets(VectorG off,
                               VectorG err)

Sets the measured zenith distance offsets and the erros, if available. The unit of the offset defines the unit of the fitting parameters, i.e. you can use arcminutes, degrees or radians here.

Parameters:

off - The measured offsets in zenith distance.

err - Measurement errors or null.

getAzimuthSolution

public VectorG getAzimuthSolution()

Fits the offsets to the azimuth model using linear regression. If bootstrapping is disabled, we also set the sigmas of the solution using the diagonal elements of the covariance matrix in the linear model. This method call is the only possibility to set chi^2 and the quality of the solution.

getAltitudeSolution

public VectorG getAltitudeSolution()

Fits the offsets to the altitude model using linear regression. If bootstrapping is disabled, we also set the sigmas of the solution using the diagonal elements of the covariance matrix in the linear model.

getAzimuthSigma

public VectorG getAzimuthSigma()

Returns the sigma of the azimuth model. If bootstrapping is enabled, the sigma is calculated via a bootstrapping algoirthm, which is costly in time, but more reliable then the simple covariance matrix analysis done, if bootstrapping is disabled. Note that this is the only method to also set the bootstrapping statistical information azboot, azmin, and azmax.

getAltitudeSigma

public VectorG getAltitudeSigma()

Returns the sigma of the altitude model. If bootstrapping is enabled, the sigma is calculated via a bootstrapping algoirthm, which is costly in time, but more reliable then the simple covariance matrix analysis done, if bootstrapping is disabled. Note that this is the only method to also set the bootstrapping statistical information altboot, altmin, and altmax.

subtractMean

public void subtractMean(VectorG nv)

Replaces the measruements by the measurements minus their average
