Detailed Description

Provides necessary information about the Moon.

A subclass of SkyObject that provides information needed for the Moon. Specifically, KSMoon provides a moon-specific findPosition() function. Also, there is a method findPhase(), which returns the lunar phase as a floating-point number between 0.0 and 1.0.

Member Function Documentation

clone()

KSMoon * KSMoon::clone ( ) const

overridevirtual

Create copy of object.

This method is virtual copy constructor. It allows for safe copying of objects. In other words, KSPlanet object stored in SkyObject pointer will be copied as KSPlanet.

Each subclass of SkyObject MUST implement clone method. There is no checking to ensure this, though.

Returns

pointer to newly allocated object. Caller takes full responsibility for deallocating it.

Reimplemented from SkyObject.

Definition at line 76 of file ksmoon.cpp.

findGeocentricPosition()

bool KSMoon::findGeocentricPosition ( const KSNumbers * num, const KSPlanetBase *  )

overridevirtual

Reimplemented from KSPlanetBase, this function employs unique algorithms for estimating the lunar coordinates.

Finding the position of the moon is much more difficult than the other planets. For one thing, the Moon is a lot closer, so we can detect smaller deviations in its orbit. Also, the Earth has a significant effect on the Moon's orbit, and their interaction is complex and nonlinear. As a result, the positions as calculated by findPosition() are only accurate to about 10 arcseconds (10 times less precise than the planets' positions!)

moon-specific coordinate finder

Parameters

num	KSNumbers pointer for the target date/time

Note

we don't use the Earth pointer here

Implements KSPlanetBase.

Definition at line 153 of file ksmoon.cpp.

findPhase() [1/2]

void KSPlanetBase::findPhase ( )

virtual

Determine the phase of the planet.

Reimplemented from KSPlanetBase.

Definition at line 250 of file ksplanetbase.cpp.

findPhase() [2/2]

void KSMoon::findPhase

(

const KSSun *

Sun = nullptr

)

Determine the phase angle of the moon, and assign the appropriate moon image.

Parameters

Sun	a KSSun pointer with coordinates updated to the time of computation. If not supplied, the sun is retrieved via KStarsData

Note

Overrides KSPlanetBase::findPhase()

Definition at line 268 of file ksmoon.cpp.

getIPhase()

short int KSMoon::getIPhase ( ) const

inline

Returns

iPhase, which is used as a key to find the right image file

Definition at line 58 of file ksmoon.h.

getUID()

SkyObject::UID KSMoon::getUID ( ) const

overridevirtual

Return UID for object.

This method should be reimplemented in all concrete subclasses. Implementation for SkyObject just returns invalidUID. It's required SkyObject is not an abstract class.

Reimplemented from SkyObject.

Definition at line 329 of file ksmoon.cpp.

illum()

double KSMoon::illum ( ) const

inline

Returns

the illuminated fraction of the Moon as seen from Earth

Definition at line 49 of file ksmoon.h.

initPopupMenu()

void KSMoon::initPopupMenu ( KSPopupMenu * pmenu )

overridevirtual

Initialize the popup menut.

This function should call correct initialization function in KSPopupMenu. By overloading the function, we don't have to check the object type when we need the menu.

Reimplemented from SkyObject.

Definition at line 320 of file ksmoon.cpp.

loadData()

bool KSMoon::loadData ( )

overridevirtual

reimplemented from KSPlanetBase

Implements KSPlanetBase.

Definition at line 98 of file ksmoon.cpp.

phaseName()

QString KSMoon::phaseName

(

)

const

Returns

a short string describing the moon's phase

Definition at line 288 of file ksmoon.cpp.

updateMag()

void KSMoon::updateMag ( )

inline

updateMag calls findMagnitude() to calculate current magnitude of moon according to current phase.

This function is required to perform findMagnitude() from any where in Kstars
