cds-question@unistra.frdwarf-galaxiesstar-forming-regionsvisible-astronomyspectroscopyredshiftedThe Star Formation Across Cosmic Time (SFACT) survey is a new narrowband survey designed to detect emission-line galaxies (ELGs) and quasi-stellar objects (QSOs) over a wide range of redshifts in discrete redshift windows. The survey utilizes the WIYN 3.5m telescope and the Hydra multifiber positioner to perform efficient follow-up spectroscopy on galaxies identified in the imaging part of the survey. Because the objects in the SFACT survey are selected by their strong emission lines, it is possible to obtain useful spectra for even the faintest of our sources (r~25). Here, we present the 453 objects that have spectroscopic data from the three SFACT pilot-study fields, 415 of which are confirmed ELGs. The methodology for processing and measuring these data is outlined in this paper, and example spectra are displayed for each of the three primary emission lines used to detect objects in the survey (H{alpha}, [OIII]{lambda}5007, and [OII]{lambda}3727). Spectra of additional QSOs and nonprimary-emission-line detections are also shown as examples. The redshift distribution of the pilot-study sample is examined, and the ELGs are placed in different emission-line diagnostic diagrams in order to distinguish the star-forming galaxies from the active galactic nuclei.2023AJ....166..102Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/166/102CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/337 : Gaia DR1 (Gaia Collaboration, 2016)I/350 : Gaia EDR3 (Gaia Collaboration, 2020)J/ApJS/95/387 : Universidad Complutense de Madrid list 1 (Zamorano+ 1994)J/ApJS/105/343 : Universidad Complutense de Madrid list 2 (Zamorano+ 1996)J/A+AS/135/511 : The Hamburg/SAO Survey for ELGs (Ugryumov+ 1999)J/A+AS/142/417 : Hamburg/SAO Survey for ELGs.
