Module API¶
- pyspeckit.spectrum.models.hill5infall.hill5_model(xarr, tau, v_lsr, v_infall, sigma, tpeak, TBG=2.73)[source] [github] [bitbucket]¶
The hill5 from de Vries and Myers 2005. This model implicitly has zero optical depth in the envelope, no envelope velocity, and has a fixed background radiation temperature (see Table 2 in the paper).
- Parameters
xarr : np.ndarray
array of x values
tau : float
tau_c, the core-center optical depth
v_lsr : float
The centroid velocity in km/s
v_infall : float
The infall velocity
sigma : float
The line width
tpeak : float
The peak brightness temperature
TBG : float
The background temperature
