Constructor Detail

StarProspect

public StarProspect(Point2D c,
                    double m)

StarProspect

public StarProspect(Point2D c,
                    double poserr,
                    double m,
                    double magerr)

Method Detail

getPositionError

public double getPositionError()

The right ascension and declination errors of the star given by the star catalog give rise to an individual error of the pixel position of the star. This is the square root of the sum of the right ascension and declination errors squared, if propagated onto this detector.

Returns:

the positional error in pixel

getMagnitudeError

public double getMagnitudeError()

Transformation of the catalog magnitude will yield a color-dependent magnitude error if propagated to this detector's QE curve. This method returns an estimate of this error.

Returns:

the magnitude error in mags.

toShortString

public String toShortString()

Prints the coordinates and the magnitude, separated by spaces.

toString

public String toString()

Prints the coordinates and the magnitude, separated by spaces.

Overrides:
