A common form is the n(x)dx = Φ - x - L/L
_{Sun}(luminosity in solar luminosities). - Φ
_{Sun}- a factor to normalize the Number Density, chosen to match observation, in units of h^{3}/Mpc^{3}(parameter). - a - a power, chosen to match observation (parameter).
- h - normalized Hubble Constant (H
_{0}).
Some typical values of the plug-in parameters: - a = -1.25
- Φ
_{Sun}= 1.2 × 10^{-3}
