Detailed Description

This class deals with the observing conditions of the night sky.

The limiting magnitude is calculated depending on the equipment available to the user and the amount of light-pollution in the user's current observing location.

Member Function Documentation

getOptimumMAG()

double ObsConditions::getOptimumMAG

(

)

Get optimum magnification under current observing conditions.

Returns

Get optimum magnification under current observing conditions

Definition at line 57 of file obsconditions.cpp.

getTrueMagLim()

double ObsConditions::getTrueMagLim

(

)

Get true limiting magnitude after taking equipment specifications into consideration.

Returns

True limiting magnitude after taking equipment specifications into consideration.

If there is no equipment available then return limiting magnitude for naked-eye

This is a more traditional formula which does not take the 't' parameter into account. It also does not take into account the magnification being used. The formula used is:

TLM_trad = LM + 5*log10(aperture/7.5)

The calculation is just based on the calculation of the telescope's aperture to eye's pupil surface ratio.

Definition at line 63 of file obsconditions.cpp.

isVisible()

bool ObsConditions::isVisible	(	GeoLocation *	geo,
		dms *	lst,
		SkyObject *	so )

Evaluate visibility of sky-object based on current observing conditions.

Parameters

geo	Geographic location of user.
lst	Local standard time expressed as a dms object.
so	SkyObject for which visibility is to be evaluated.

Returns

Visibility of sky-object based on current observing conditions as a boolean.

Definition at line 86 of file obsconditions.cpp.

setEquipment()

void ObsConditions::setEquipment ( Equipment equip )

inline

Inline method to set available equipment.

Definition at line 62 of file obsconditions.h.

setLimMagnitude()

void ObsConditions::setLimMagnitude

(

)

Set limiting magnitude depending on Bortle dark-sky rating.

Definition at line 52 of file obsconditions.cpp.

setLMMap()

QMap< int, double > ObsConditions::setLMMap ( )

static

Create QMap<int, double> to be initialised to static member variable m_LMMap.

Returns

Definition at line 34 of file obsconditions.cpp.

setObsConditions()

void ObsConditions::setObsConditions	(	int	bortle,
		double	aperture,
		ObsConditions::Equipment	equip,
