An instance of the MappingsSEDFamily class represents the family of MAPPINGS III star-forming region template SEDs, parameterized on metallicity, compactness, ISM pressure and PDR covering factor, and scaled by star formation rate, as described by Groves et al. 2008 (ApJS,176,438). The model spectra have 1800 wavelength bins and cover 5 metallicities, 6 compactness parameters, 5 pressure values, and 2 covering factors (0 for pure HII and 1 for 100% PDR).
The SEDs are tabulated over a wavelength range from 1 Angstrom to almost 1 meter with the spectral resolution shown in the figure below.
The data were downloaded from http://www.mpia-hd.mpg.de/~brent/starburst.html -> Cparam_models.save, however it seems that this page/download is no longer available. The contents of the IDL save file were converted to SKIRT stored table format for inclusion as a resource file. The stored table is opened during setup, and it is subsequently interpolated to the desired parameters and wavelength grid when needed.
When imported from a text column file, the properties of the star-forming region represented by this SED family must appear in the following order, and have the specified default units unless these units are overridden by column header info:
\[ \dot{M}\,(\mathrm{M}_\odot\,{\text{yr}}^{-1}) \quad Z\,(\mathrm{dimless}) \quad \log C\,(\mathrm{dimless}) \quad p\,(\mathrm{Pa}) \quad f_{\text{PDR}}\,(\mathrm{dimless}) \]
where \(\dot{M}\) is the star formation rate, assumed to be constant over the past 10 Myr, \(Z\) is the metallicity, \(\log C\) is the logarithm of the compactness, \(p\) is the ISM pressure, and \(f_{\text{PDR}}\) is the PDR covering factor.
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.

Default constructor for concrete Item subclass MappingsSEDFamily : "a MAPPINGS III SED family for star-forming regions" .
|
explicit |
This constructor can be invoked programmatically by classes that use a hard-coded SED family (as opposed to selected through the ski file). Before the constructor returns, the newly created object is hooked up as a child to the specified parent in the simulation hierarchy (so it will automatically be deleted), and its setup() function has been called.
|
overridevirtual |
This function constructs both the normalized probability density function (pdf) and the corresponding normalized cumulative distribution function (cdf) for the SED with the specified parameters over the specified wavelength range. The function returns the normalization factor. The number and type of parameters must match the information returned by the parameterInfo() function; if not the behavior is undefined.
Implements SEDFamily.
|
overridevirtual |
This function returns the intrinsic wavelength range of the SED family. It retrieves this range from the underlying stored table.
Implements SEDFamily.
|
overridevirtual |
This function returns the number and type of parameters used by this particular SED family as a list of SnapshotParameter objects. Each of these objects specifies unit information and a human-readable descripton for the parameter.
Implements SEDFamily.
|
overrideprotectedvirtual |
This function opens the appropriate resource file (in SKIRT stored table format).
Reimplemented from SimulationItem.
|
overridevirtual |
This function returns the specific luminosity \(L_\lambda\) (i.e. radiative power per unit of wavelength) for the SED with the specified parameters at the specified wavelength, or zero if the wavelength is outside of the SED's intrinsic wavelength range. The number and type of parameters must match the information returned by the parameterInfo() function; if not the behavior is undefined.
Implements SEDFamily.
