Ca4227 indices in early-type galaxies
Listed in IVOA Registry (Virtual Observatory)
We have investigated the abundance of calcium in early-type galaxies by measuring the strength of the CaI {lambda}4227 absorption line in their integrated spectra.
Description
The database used is the large sample of early-type galaxy integrated spectra in Caldwell and coworkers (2003AJ....125.2891C). We have measured Ca abundances from the CaI {lambda}4227 feature both by using the Lick Ca4227 index and by defining a new index, Ca4227_r_, that avoids the CN4216 molecular band in the continuum on the blueward side of the line.
