| Abstract: |
We present EZ, a software for the automatic measurement of spectroscopic parameters, with a particular attention to redshifts. It is an open source software developed by the PANDORA Group in collaboration with Osservatorio Monte Porzio (Roma) and Integral Science Data Center (Geneve). EZ has been publicly released in June 2007, on the PANDORA web site: http://cosmos.iasf-milano.inaf.it/pandora/EZ.html. The main ingredients of EZ are: a custom spectrum templates set, a combination of cross-correlation and fitting algorithms and a decisional tree which drives EZ computations. The software supports the PLASTIC messaging system, and it is also able to retrieve data from the Virtual Observatory, accessing SSA services through the VO registries. During its development, EZ has been tested on VVDS and zCOSMOS data, obtaining a redshift measurement accuracy success rate of 80% (with peaks of 95%). We are currently adding new functionalities to measure main spectral features, like line equivalent widths and fluxes. |
