Differences in carbon and nitrogen abundances between field and cluster early-type galaxies
P. Sanchez-Blazquez, J. Gorgas, N. Cardiel +2
Central line-strength indices were measured in the blue spectral region for a sample of 98 early-type galaxies in different environments. For most indices (Mgb and <Fe> in particul…

Reliable random error estimation in the measurement of line-strength indices
N. Cardiel, J. Gorgas, J. Cenarro +1
We present a new set of accurate formulae for the computation of random errors in the measurement of atomic and molecular indices. The new expressions are in excellent agreement wi…
