Function Documentation

def pyneb.utils.stellar.BC

(

T_eff

)

Bolometric correction for very hot stars, from Vacca, Garmany & Shull,
   1996, ApJ, 460, 914.

def pyneb.utils.stellar.G	(		ion,
			T
	)

Compute integral over frequency for Planck function.
   ion - Reference Ion ("H | HE')
   T   - Stellar temperature (K)
   See Pottasch (1984), p. 169, eq. VII-8 for details. 

def pyneb.utils.stellar.integrand

(

x

)

def pyneb.utils.stellar.logL	(		V,
			D_pc,
			T_eff
	)

Calculate the stellar luminosity in Solar units, given an (unreddened) V 
   apparent magnitude, a distance (pc), and the stellar temperature (K).
