Parameters

HDnum

Henry-Draper catalog number of the desired star

Returns

A star matching the given Henry-Draper catalog number

BinFileHelper* DeepStarComponent::getStarReader ( )

inline

Definition at line 92 of file deepstarcomponent.h.

bool DeepStarComponent::hasStaticStars ( )

inline

Returns

true if this DeepStarComponent has static stars (that are not dynamically loaded)

Definition at line 72 of file deepstarcomponent.h.

bool DeepStarComponent::loadStaticStars

(

)

Definition at line 59 of file deepstarcomponent.cpp.

SkyObject * DeepStarComponent::objectNearest ( SkyPoint *  p, double &  maxrad  )

virtual

Returns

Nearest star within maxrad of SkyPoint p, or NULL if not found

Reimplemented from ListComponent.

Definition at line 370 of file deepstarcomponent.cpp.

bool DeepStarComponent::openDataFile

(

)

Definition at line 308 of file deepstarcomponent.cpp.

bool DeepStarComponent::selected ( )

virtual

Returns

true if component is to be drawn on the map.

Reimplemented from SkyComponent.

Definition at line 155 of file deepstarcomponent.cpp.

bool DeepStarComponent::starsInAperture	(	QList< StarObject * > &	list,
		const SkyPoint &	center,
		float	radius,
		float	maglim = -29
	)

Add to the given list, the stars from this component, that lie within the specified circular aperture, and that are brighter than the limiting magnitude specified.

center The center point of the aperture radius The radius around the center point that defines the aperture maglim Optional parameter indicating the limiting magnitude. If magnitude limit is numerically < -28, the limiting magnitude is assumed to be the limiting magnitude of the catalog (i.e. no magnitude limit) list The list to operate on

Returns

false if the limiting magnitude is brighter than the trigger magnitude of the DeepStarComponent

Definition at line 410 of file deepstarcomponent.cpp.

void DeepStarComponent::update ( KSNumbers *  num )

virtual

Update the sky positions of this component.

This function usually just updates the Horizontal (Azimuth/Altitude) coordinates of the objects in this component. If the KSNumbers* argument is not NULL, this function also recomputes precession and nutation for the date in KSNumbers. num Pointer to the KSNumbers object

Note

By default, the num parameter is NULL, indicating that Precession/Nutation computation should be skipped; this computation is only occasionally required.

Reimplemented from ListComponent.
