示例1: add_abslines_from_linelist
# 需要導入模塊: from linetools.lists.linelist import LineList [as 別名]
# 或者: from linetools.lists.linelist.LineList import from_dict_to_qtable [as 別名]
def add_abslines_from_linelist(self, llist='ISM', wvlim=None, min_Wr=None, **kwargs):
"""
It adds associated AbsLines satisfying some conditions (see parameters below).
Parameters
----------
llist : str
Name of the linetools.lists.linelist.LineList
object where to look for the transition names.
Default is 'ISM', which means the function looks
within `list = LineList('ISM')`.
wvlims : Quantity array, optional
Observed wavelength limits for AbsLines to be added.
e.g. [1200, 2000]*u.AA.
min_Wr : Quantity, optional
Minimum rest-frame equivalent with for AbsLines to be added.
This is calculated in the very low optical depth regime tau0<<1,
where Wr is independent of Doppler parameter or gamma (see eq. 9.15 of
Draine 2011). Still, a column density attribute for the AbsComponent
is needed.
Returns
-------
Adds AbsLine objects to the AbsComponent._abslines list.
Notes
-----
**kwargs are passed to AbsLine.add_absline() method.
