Reference/API¶
dust_emissivity Package¶
This is an Astropy affiliated package.
dust_emissivity.dust Module¶
Functions¶
colofsnu(nu, snu_per_beam[, temperature, muh2]) |
|
kappa(nu[, nu0, kappa0, beta]) |
Compute the opacity $kappa$ given a reference frequency (or wavelength) |
kappa_table(nu[, url]) |
Use an opacity table to compute kappa |
massofsnu(nu, snu[, distance, temperature, ...]) |
|
planck_average_kappa(temperature[, kappa]) |
Compute the Blackbody-weighted opacity assuming a power law dust |
planck_average_kappa_table(temperature[, ...]) |
|
quad(func, a, b[, args, full_output, ...]) |
Compute a definite integral. |
snu(nu, column, kappa, temperature) |
Compute the flux density for a given column of gas assuming some opacity kappa |
snudnu(nu, column, kappa, temperature, bandwidth) |
|
snuofmass(nu, mass[, beamomega, distance, ...]) |
Flux density for a given mass and beam area |
tauofsnu(nu, snu_per_beam[, temperature]) |
nu in GHz |
dust_emissivity.blackbody Module¶
Includes both wavelength and frequency blackbody functions. Has flexible units. Also allows for a few varieties of modified blackbody.
Functions¶
blackbody(nu, temperature[, outunit]) |
Planck’s Law Blackbody (Frequency units) |
blackbody_wavelength(lam, temperature[, outunit]) |
|
integrate_sed(vmin, vmax[, function]) |
Integrate one of the SED functions over frequency |
modified_blackbody(nu, temperature[, beta, ...]) |
Snu = 2hnu^3 c^-2 (e^(hnu/kT) - 1)^-1 (1 - e^(-tau_nu) ) Kappa0 and Nu0 are set as per http://arxiv.org/abs/1101.4654 which uses OH94 values. |
dust_emissivity.fit_sed Module¶
Functions¶
blackbody(nu, temperature[, outunit]) |
Planck’s Law Blackbody (Frequency units) | ||
fit_modified_bb(xdata, flux, error, guesses) |
Wrapper SED fitter that uses astropy’s units and returns the fitted | ||
fit_modifiedbb_montecarlo(frequency, flux[, ...]) |
An MCMC version of the fitter. | ||
fit_sed_lmfit_hz(xdata, flux[, guesses, ...]) |
|
||
fit_sed_mpfit_hz(xdata, flux[, guesses, ...]) |
|
||
modified_blackbody(nu, temperature[, beta, ...]) |
Snu = 2hnu^3 c^-2 (e^(hnu/kT) - 1)^-1 (1 - e^(-tau_nu) ) Kappa0 and Nu0 are set as per http://arxiv.org/abs/1101.4654 which uses OH94 values. |
