示例1: complist_from_table
# 需要导入模块: from linetools.isgm.abscomponent import AbsComponent [as 别名]
# 或者: from linetools.isgm.abscomponent.AbsComponent import attrib[key] [as 别名]
def complist_from_table(table):
"""
Returns a list of AbsComponents from an input astropy.Table.
Parameters
----------
table : Table
Table with component information (each row must correspond
to a component).
Each column is expecting a unit when appropriate.
Units for vmin, vmax are assumed km/s if not given
Units for Ej are assumed cm^-1 if not given
Returns
-------
complist : list
List of AbsComponents defined from the input table.
Notes
-----
Mandatory column names: 'RA', 'DEC', 'ion_name', 'z_comp', 'vmin', 'vmax'
These column are required.
Special column names: 'name', 'comment', 'logN', 'sig_logN', 'flag_logN'
These columns will fill internal attributes when corresponding.
In order to fill in the Ntuple attribute all three 'logN', 'sig_logN', 'flag_logN'
must be present. For convenience 'logN' and 'sig_logN' are expected to be floats
corresponding to their values in np.log10(1/cm^2).
Other columns: 'any_column_name'
These will be added as attributes within the AbsComponent.attrib dictionary,
with their respective units if given.
