LumFunc:
A numerical code to model the Luminosity Function based on central galaxy luminosity-halo mass and total galaxy luminosity-halo mass relations.

If you use this code for your work, please acknowledge its use with a citation to Cooray & Milosavljevic (2005, ApJ, 627, L89).
The code can handle rest b_J-band (2dFGRS), r'-band (SDSS), and K-band luminosities, and any redshift with redshift dependences specified by the user. It separates the luminosity function (LF) to conditional luminosity functions, LF as a function of halo mass, and also to galaxy types.
By specifiying a narrow mass range, the code will return the
conditional luminosity functions. The code returns luminosity functions
for galaxy types as well (broadly divided to early-type and late-type).
The code also models the cluster luminosity function, either mass averaged or for individual clusters.
The future versions of the code will be updated to handle other bands, and to extract model parameters of the L-central(M) relation given the observed luminosity function, and to model fit galaxy clustering measurements.
