fluorescence_band_strength

sbpy.activity.fluorescence_band_strength(species, eph=None, source=None)[source]

Fluorescence band strength.

Parameters
speciesstring

Species to look up.

ephQuantity, Ephem or dict optional

The target ephemeris. The strength is scaled to the given heliocentric distance, if present. Some species require heliocentric radial velocity (‘rdot’).

sourcestring, optional

Retrieve values from this source (case insensitive). See references for keys.

Returns
LNQuantity

Luminosity per molecule, scaled to rh, if provided.

Examples

>>> import astropy.units as u
>>> from sbpy.activity import fluorescence_band_strength
>>>
>>> eph = {'rh': 1 * u.au, 'rdot': -1 * u.km / u.s}
>>> LN = fluorescence_band_strength('OH 0-0', eph, 'SA88')
>>> print(LN)    # doctest: +FLOAT_CMP
