J/ApJ/411/501 I-band selected galaxy sample (Lilly, 1993)
A deep I-band selected galaxy sample : implications for galaxy evolution. Lilly S.J. <Astrophys. J. 411, 501 (1993)> =1993ApJ...411..501L (SIMBAD/NED BibCode)
ADC_Keywords: Infrared sources ; Galaxies, IR ; Redshifts ; Equivalent widths Keywords: galaxies: distances and redshifts - galaxies: evolution - galaxies: formation - infrared: galaxies Abstract: New spectroscopic observations of statistically complete sample of 50 very faint I-band selected galaxies with IAB<22.5 show that, although they extend out to z∼1, the redshifts are generally low, <z>obs∼0.5±0.1.

Note (1): Notes: g: Redshift taken from LCG (Lilliy et al., 1991ApJ...369...79L): no. 113 (=LCG SSA 22-01), no. 120 (=LCG SSA 22-03), no. 86 (=LCG SSA 22-Anon A), and no. 108 (=LCG SSA 22-07). f: Redshift from unpublished spectrum taken as part of LCG h: Object identified in LCG photometric catalog but without previous spectroscopic observations: no. 126 (=LCG SSA 22-05) and no. 25 (=LCG SSA 22-07) Note (2): Positions X and Y are approximate and are in arcsec east and north, respectively, from no. 113 (= SSA 22.01 of LCG) which has position RA = 22 15 0.13 (1950) DE = -00 00 01 Note (3): Quality class: A: more than one compelling feature (32 of the 50 objects including seven stars B: a single definite feature (e.g., a single bright emission line identified with [O II] 3727) where other expected features are only weakly seen or plausibly absent (nine objects most of which are at z>0.7) C: a number of consistent weak features or a single strong feature where other supporting features might reasonably have been seen but where not (three objects). D: no identification claimed (seven objects). Note (4): No reddening corrections have been applied to the (V-I)AB color which is measured in the 3" aperture.
