\caption{Typical values of the different considered error sources. Phot.:
photonic noise; Flux: flux calibration; Wave.: wavelength calibration; Dichr.:
typical error in the subtraction of the dichroic pattern (this error is only
added in the measurements of Run 2). Res.: residual errors, based on repeated
observations of 10~galaxies. \label{tipicos}}
