Detailed Description

LineSED is an abstract class for representing spectral energy distributions that consist of one or more discrete emission lines with zero width. Mathematically, the specific luminosity is infinite at the line wavelengths and zero everywhere else, while the integrated luminosity (over all lines in the source wavelength range) is still normalized to unity. As a result, the specific luminosity is numerically undefined. This imposes important restrictions on the use of the SED:

• A LineSED must be normalized by defining the integrated luminosity over a wavelength range that includes one or more of the line wavelengths. It cannot be normalized by defining the specific luminosity at a given wavelength or for a broadband.
• The wavelength bias property of the corresponding source must be set to zero, because the mechanism for wavelength biasing relies on the specific luminosity.

The subclass must provide the list of wavelengths and corresponding relative luminosities, and this abstract class handles everything else.

This item type is allowed only if the Boolean expression "Panchromatic" evaluates to true after replacing the names by true or false depending on their presence.

This item type is displayed only if the Boolean expression "Level2" evaluates to true after replacing the names by true or false depending on their presence.

Constructor & Destructor Documentation

LineSED()

LineSED::LineSED ( )

inlineprotected

Default constructor for abstract Item subclass LineSED : "a spectral energy distribution consisting of discrete lines" .

Member Function Documentation

generateWavelength()

double LineSED::generateWavelength ( ) const

overridevirtual

This function draws a random wavelength from the normalized spectral energy distribution. For the current class, it chooses one of the line wavelengths.

Implements SED.

Reimplemented in SingleWavelengthSED.

getWavelengthsAndLuminosities()

virtual void LineSED::getWavelengthsAndLuminosities ( Array &  lambdav, Array &  Lv  ) const

protectedpure virtual

This function must be implemented in each subclass to return the wavelengths and the corresponding relative luminosities defining the lines in the SED. The function must guarantee that both arrays have the same size. The order of the pairs (other than the correspondance between a wavelength and its luminosity) is not important. Constant scaling of the luminosities is not important because the SED will be normalized by this abstract class.

Implemented in FileLineSED, ListLineSED, and SingleWavelengthSED.

integratedLuminosity()

double LineSED::integratedLuminosity ( const Range &  wavelengthRange ) const

overridevirtual

This function returns the normalized integrated luminosity $L$ (i.e. radiative power) over the specified wavelength range. For the current class, this corresponds to the sum of the normalized luminosities for all lines with a wavelength in the specified range.

Implements SED.

intrinsicWavelengthRange()

Range LineSED::intrinsicWavelengthRange ( ) const

overridevirtual

This function returns the intrinsic wavelength range of the SED. For the current class, the range includes all line wavelengths.

Implements SED.

setupSelfBefore()

void LineSED::setupSelfBefore ( )

overrideprotectedvirtual

This function asks the subclass to load the wavelength/luminosity pairs for one or more lines and precalculates the information needed by the other functions in this class.

Reimplemented from SimulationItem.
