= Galactic stellar mass function
{synonym}
The <galaxy stellar mass function> counts galaxies per stellar-mass interval and volume, often using <comoving volume>. Its stellar-mass moment gives the <cosmic stellar mass density>, while its number moment counts galaxies only if the low-mass population is integrable or truncated. It differs from the initial mass function of individual stars.
