fluorescence_band_strength¶
- sbpy.activity.gas.core.fluorescence_band_strength(species, eph=None, source=None)[source]¶
Fluorescence band strength.
- Parameters
- speciesstring
Species to look up.
- eph
Quantity
,Ephem
ordict
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
- LN
Quantity
Luminosity per molecule, scaled to rh, if provided.
- LN
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) [1.54e-15] erg / s
