LE PHARE
PHotometric Analysis for Redshift Estimations
Stephane ARNOUTS & Olivier ILBERT

  Last  UPDATE  :  version from April 09


Goal :

Le PHARE is a set of fortran commands to compute photometric redshifts and to perform SED fitting. The last version includes new features with FIR fitting and a more complete treatment of physical parameters and uncertainties based on PEGASE and Bruzual & Charlot  population synthesis models.


Le PHARE's structure is divided in three parts:


  1. 1.   A preliminary phase where the user selects the SED libraries and filter bands

  2.          and computes theoretical magnitudes.  The different programs have been developed in order to easily get basic informations relative to the filters (lambda mean, AB-corrections, ...) and SEDs (magnitudes & k-corrections vs z, color-color diagrams, ...).


  3. 2.  The photometric redshift program.  The program is based on a  simple chi2 fitting method between the theoretical  and observed photometric catalogue.


  4. 3.  A simulation program is also available in order to generate realistic multi-colour catalogues taking into account observational effects.

  5.                      (not working for the moment with the new version...)
