EmLine Class¶
Notebooks¶
Overview¶
This Class is a child of the abstract SpectralLine Class Class. See that documentation for the base methods.
EmLine is designed to organize and analyze an emission line. In addition to the attributes defaulted to SpectralLine, this class has:
| Property | Variable | Type | Description |
|---|---|---|---|
| Flux | attrib[‘flux’] | Quantity | Line flux (erg/s) |
| Flux sigma | attrib[‘sig_flux’] | Quantity | 1 sigma uncertainty in flux |
| Flux flag | attrib[‘flag_flux’] | int | Flux flag |
Instantiation¶
The typical way to instantiate is a standard call with the rest wavelength or name of the transition:
emisslin = EmLine('Halpha')
emisslin = EmLine(6564.613*u.AA)
By default the class searches the Galaxy LineList.
from_dict¶
Instantiate from a dict. The keys ltype (‘Em’) and trans are required.
