ScalarAtmosphericDensity Class 
Namespace: AGI.Foundation.Celestial
The ScalarAtmosphericDensity type exposes the following members.
Name  Description  

ScalarAtmosphericDensity  Initializes a Scalar representing atmospheric density. TargetPoint and SolarGeophysicalData must be set before an evaluator is created.  
ScalarAtmosphericDensity(Point, SolarGeophysicalData) 
Initializes a Scalar representing atmospheric density using the target point
and solargeophysical data.
 
ScalarAtmosphericDensity(ScalarAtmosphericDensity, CopyContext)  Initializes a new instance as a copy of an existing instance.  
ScalarAtmosphericDensity(Point, SolarGeophysicalData, CentralBody, Vector) 
Initializes a Scalar representing atmospheric density using the target point
and solargeophysical data.

Name  Description  

CentralBody 
Gets or sets the central body of the atmosphere described by the density model. This is set to the Earth by default.
 
IsFrozen 
Gets a value indicating whether this object is frozen. A frozen object cannot be modified and an
ObjectFrozenException will be thrown if an attempt is made to do so.
(Inherited from DefinitionalObject.)  
LowerHeightLimit 
Gets the lower bound of the height (in meters above the ellipsoid) for which the density model is valid.
 
SolarGeophysicalData 
Gets or sets the solar and magnetic flux information.
 
TargetPoint 
Gets or sets the target point describing the timevarying position at which density is
to be calculated.
 
UpperHeightLimit 
Gets the upper bound of the height (in meters above the ellipsoid) above which the density model will return a value of zero.
 
VectorToSun 
Gets or sets the vector to the sun to use for modeling the effects of solar radiation on the atmosphere.
By default, this is set to represent the apparent displacement from the Earth
to the Sun based on light time delay and aberration from the relative
motion of the celestial bodies. Setting this to use the true displacement
will be slightly less accurate but take less time to compute. However, not all density models will use the Sun's position.

Name  Description  

Add(Double) 
Adds a fixed scalar to this one.
(Inherited from Scalar.)  
Add(Scalar) 
Adds another scalar to this one.
(Inherited from Scalar.)  
CheckForSameDefinition(DefinitionalObject) 
Checks to determine if another instance has the same definition as this instance and
returns if it does. Derived classes MUST override this method and check
all new fields introduced by the derived class for definitional equivalence. It is NOT necessary
to check base class fields because the base class will already have done that. When overriding this method,
you should NOT call the base implementation because it will return for all derivedclass instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
(Inherited from Scalar.)  
CheckForSameDefinition(Scalar) 
Checks to determine if another instance has the same definition as this instance and
returns if it does. Derived classes MUST override this method and check
all new fields introduced by the derived class for definitional equivalence. It is NOT necessary
to check base class fields because the base class will already have done that. When overriding this method,
you should NOT call the base implementation because it will return for all derivedclass instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
(Overrides ScalarCheckForSameDefinition(Scalar).)  
CheckForSameDefinition(ScalarAtmosphericDensity) 
Checks to determine if another instance has the same definition as this instance and
returns if it does. Derived classes MUST override this method and check
all new fields introduced by the derived class for definitional equivalence. It is NOT necessary
to check base class fields because the base class will already have done that. When overriding this method,
you should NOT call the base implementation because it will return for all derivedclass instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
 
Clone 
Clones this object using the specified context.
(Inherited from DefinitionalObject.)  
ComputeCurrentDefinitionHashCode 
Computes a hash code based on the current properties of this object. Derived classes MUST override this
method and compute a hash code that combines: a unique hash code seed, the base implementation result, and
the hash codes of all new fields introduced by the derived class which are used in the
CheckForSameDefinition(DefinitionalObject) method.
(Overrides ScalarComputeCurrentDefinitionHashCode.)  
CreateScalarDerivative 
Constructs a scalar which represents a derivative of this scalar.
(Inherited from Scalar.)  
Divide(Double) 
Divides this scalar (numerator) by a fixed value (denominator).
(Inherited from Scalar.)  
Divide(Scalar) 
Divides this scalar (numerator) by another one (denominator).
(Inherited from Scalar.)  
EnumerateDependencies 
Enumerates the dependencies of this object by calling
EnumerateT(T) for each object that this object directly depends upon.
Derived classes which contain additional dependencies MUST override this method, call the base
implementation, and enumerate dependencies introduced by the derived class.
(Overrides DefinitionalObjectEnumerateDependencies(DependencyEnumerator).)  
Equals  Determines whether the specified object is equal to the current object. (Inherited from Object.)  
Finalize  Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)  
Freeze 
Freezes this object. Further attempts to modify it will result
in an ObjectFrozenException.
(Inherited from DefinitionalObject.)  
FreezeAggregatedObjects 
Called by Freeze to also freeze any objects that are considered to be a part of this object.
Derived classes which contain additional aggregated objects MUST override this method, call the base
implementation, and freeze aggregated objects introduced by the derived class. The objects that need to be
frozen in this method are frequently created in this object's constructor and are not settable via
properties.
(Inherited from DefinitionalObject.)  
GetDefinitionHashCode 
Gets a hash code representing the definition of this object.
(Inherited from DefinitionalObject.)  
GetEvaluator 
Gets an evaluator that can be used to find the value of this scalar function at a given JulianDate.
(Inherited from Scalar.)  
GetEvaluator(EvaluatorGroup) 
Gets an evaluator that can be used to find the value of this scalar function at a given JulianDate.
Adds the evaluator to the EvaluatorGroup.
(Inherited from Scalar.)  
GetHashCode  Serves as the default hash function. (Inherited from Object.)  
GetType  Gets the Type of the current instance. (Inherited from Object.)  
IsSameDefinition 
Determines if this object has the same definition as another object.
(Inherited from DefinitionalObject.)  
MemberwiseClone  Creates a shallow copy of the current Object. (Inherited from Object.)  
Multiply(Double) 
Multiplies this scalar with a fixed value.
(Inherited from Scalar.)  
Multiply(Scalar) 
Multiplies another scalar with this one.
(Inherited from Scalar.)  
Power 
Raises this scalar to the given fixed exponent.
(Inherited from Scalar.)  
SetApparentSunPosition  
SetTrueSunPosition  
Subtract(Double) 
Subtracts a fixed scalar from this one.
(Inherited from Scalar.)  
Subtract(Scalar) 
Subtracts another scalar from this one.
(Inherited from Scalar.)  
ThrowIfFrozen 
Throws ObjectFrozenException if this object IsFrozen.
This method should be called from any method or property that modifies this object.
(Inherited from DefinitionalObject.)  
ToString  Returns a string that represents the current object. (Inherited from Object.)
