Star Formation Across Cosmic Time (SFACT) is a new narrowband survey designed
to detect faint emission-line galaxies and QSOs over a broad range of
redshifts. Here we present the first list of SFACT candidates from our
pilot-study fields. Using the WIYN 3.5m telescope, we are able to achieve good
image quality with excellent depth and routinely detect ELGs to r = 25.0. The
limiting line flux of the survey is ~1.0 x 10^16 erg/s/cm^2. SFACT targets
three primary emission lines: H-alpha, [O III]5007, and [O II]3727. The
corresponding redshift windows allow for the detection of objects at z ~ 0-1.
With a coverage of 1.50 square degrees in our three pilot-study fields, a total
of 533 SFACT candidates have been detected (355 candidates per square degree).
We detail the process by which these candidates are selected in an efficient
and primarily automated manner, then tabulate accurate coordinates, broadband
photometry, and narrowband fluxes for each source.Comment: 26 pages, 12 figures. Accepted for publication in the Astronomical
