Description:
The spectral properties of more than 400 Canada-France Redshift Survey
(CFRS) galaxies and their changes over the redshift interval 0≤z≤1.3
are investigated. Emission-line intensities and equivalent widths for
accessible lines have been measured, as well as continuum color
indices based on 200Å wide spectral regions.

Note (1): Magnitude is quoted with the AB normalization scheme (Oke,
1974ApJS...27...21O 1974ApJS...27...21O)
Note (2): D(3250-3550)=fnu(3450-3650)/fnu(3150-3350), the ratio of the
average flux density fnu in the bands 3450-3650Å and
3150-3350Å at rest, which is mostly sensitive to hot stars.
Note (3): D(3550-3850)=fnu(3750-3950)/fnu(3450-3650), which is very
sensitive to the population of A stars.
Note (4): D(4000) as defined by Bruzual (1983ApJ...273..105B 1983ApJ...273..105B), which is the
ratio of the average flux density fnu in the bands 4050-4250Å
and 3750-3950Å at rest; this index depends on both metallicity and
stellar ages.
Note (5): D(41-50)=2.5log[fnu(4900-5100)/fnu(4050-4250)], which follows the
definition of Kennicutt (1992ApJ...388..310K 1992ApJ...388..310K) and is rather
independent of the hot star population (except for the youngest
galaxies), while it varies with metalicity.
Note (6): Mg2 index, defined following Faber et al. (1977AJ.....82..941F 1977AJ.....82..941F)
and Buzzoni et al. (1992AJ....103.1814B 1992AJ....103.1814B),
Mg2=-2.5log[f(5156-5197.25)]/[0.39f(4897-4958.25)+0.61f(5303-5366.75)]
f standing for fnu, where all the flux densities correspond to
average values in the corresponding bands, either centered on the Mg
feature or at the blue and red sides, respectively: this index
depends on both temperature and metallicity (Faber et al.,
1977AJ.....82..941F 1977AJ.....82..941F; Faber et al., 1985ApJS...57..711F 1985ApJS...57..711F;
Davies et al., 1987ApJS...64..581D 1987ApJS...64..581D)
Note (7): 9999: when a line do not appear in the spectral range
9998: when a line was not measurable because of instrumental reasons
The intensity unit is the flux density integrated over the
emission line F(ν).dλ, expressed in
10-29 erg.s-1.Hz-1.cm-2*Å = erg.Å.cm-2
