Definition at line 50 of file deepstarcomponent.cpp.

objectNearest()

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

overridevirtual

Returns

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

Reimplemented from SkyComponent.

Definition at line 494 of file deepstarcomponent.cpp.

openDataFile()

bool DeepStarComponent::openDataFile

(

)

Definition at line 425 of file deepstarcomponent.cpp.

selected()

bool DeepStarComponent::selected ( )

overridevirtual

Returns

true if component is to be drawn on the map.

Reimplemented from SkyComponent.

Definition at line 209 of file deepstarcomponent.cpp.

starsInAperture()

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 552 of file deepstarcomponent.cpp.

update()

void DeepStarComponent::update ( KSNumbers * )

overridevirtual

Update the sky position(s) of this component.

This function usually just updates the Horizontal (Azimuth/Altitude) coordinates of its member object(s). However, the precession and nutation must also be recomputed periodically. num Pointer to the KSNumbers object
