Detailed Description
template<unsigned NB, unsigned NP>
class manticore::Fcost_gray< NB, NP >
Ceres solver graybody cost model.
The model consists of up to four parameters (two gas components, core and halo, each with a temperature \(T\) and mass surface density \(S\)), with the halo temperature sometimes held fixed as shown below.
| NP | Active parameters | Fixed parameters |
|---|---|---|
| 1 | Sh | Th |
| 2 | Th, Sh | - |
| 3 | Sh, Tc, Sc | Th |
| 4 | Th, Sh, Tc, Sc | - |
- Note
- This function assumes surface densities have been scaled by scale for fitting (to help normalize their magnitude relative to temperature).
- Template Parameters
-
NB Number of bands. NP Number of parameters.
