antaress.ANTARESS_grids.ANTARESS_prof_grid module

class CFunctionWrapper

Bases: object

C profile calculation

Defines the C function used in the optimization. The implementation of a class and the getstate and setstate functions is necessary to use the C function when pickling is used in emcee (when multiprocessing is used).

Stellar properties: variables

Defines variable stellar properties.

custom_DI_prof(param, x, args=None)

Disk-integrated profile: model function

Calculates custom disk-integrated stellar profile. The disk-integrated profile is built upon a discretized grid of the stellar surface to allow accounting for any type of intensity and velocity field. This routine is separated from init_custom_DI_prof() so that it can be used in fitting routines with varying parameters.

Parameters:

TBD

Returns:

TBD

Disk-integrated profile: grid initialization

Initializes stellar and intrinsic profile grids.

init_custom_DI_par(fixed_args, gen_dic, system_prop, star_params, params, RV_guess_tab)

Disk-integrated profile: parameter initialization

Initializes stellar parameters controlling either disk-integrated or local stellar grids. Fit parameters are initialized to default stellar properties.

Parameters:

TBD

Returns:

TBD

init_st_intr_prof(args, grid_dic, param)

Intrinsic stellar profiles: initialization

Initializes intrinsic profile grid and properties. Called upon initialization of the disk-integrated stellar profile grid, or in fit mode if the stellar grid or the intrinsic profile grid vary

TBD

Returns:

theo_intr2loc(grid_dic, system_prop, fixed_args, ncen_bins, nsub_star)

Intrinsic to local intensity scaling

Returns the scaling values or profiles to scale stellar line profiles from intrinsic to local in each cell.

Intrinsic spectra do not necessarily have the same flux as the disk-integrated profiles, but have been set to the same continuum or total flux (see proc_intr_data() and loc_prof_DI_mast()). Now that the intrinsic and disk-integrated profiles are equivalent in terms of flux we have \(F_\mathrm{intr}(w,t,vis) \sim F_\mathrm{DI}(w,vis)\). This is valid for broadband fluxes or the continuum of CCFs (see rescale_profiles()).

The model disk-integrated profile is defined as

\[\begin{split}F_\mathrm{DI,mod}(w,vis) &= (\sum_{\mathrm{all \, stellar \, cells}} F_\mathrm{intr}(w - w_\mathrm{shift},x,vis) \mathrm{LD}(cell,w) dS ) / A \\ & \sim (\sum_{\mathrm{all \, stellar \, cells}} F_\mathrm{DI}(w - w_\mathrm{shift},vis) \mathrm{LD}(cell,w) dS ) / A\end{split}\]

Where the shift accounts for the stellar surface velocity field. If we neglect these shifts (for spectra) or consider the continuum range (for CCF) then

\[F_\mathrm{DI,mod}(w,vis) \sim F_\mathrm{DI}(w,vis) (\sum_{\mathrm{all \, stellar \, cells}} \mathrm{LD}(cell,w) dS ) / A\]

Where A is a spectrum

\[A(w) = \sum_{\mathrm{all \, stellar \, cells}}(\mathrm{LD}(cell,w) dS )\]

If the line profile is calculated directly within the fit function we store the scaling profiles.
