Star Formation Across Cosmic Time (SFACT) is a new narrowband survey designedto detect faint emission-line galaxies and QSOs over a broad range ofredshifts. Here we present the first list of SFACT candidates from ourpilot-study fields. Using the WIYN 3.5m telescope, we are able to achieve goodimage quality with excellent depth and routinely detect ELGs to r = 25.0. Thelimiting line flux of the survey is ~1.0 x 10^16 erg/s/cm^2. SFACT targetsthree primary emission lines: H-alpha, [O III]5007, and [O II]3727. Thecorresponding 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 totalof 533 SFACT candidates have been detected (355 candidates per square degree).We detail the process by which these candidates are selected in an efficientand primarily automated manner, then tabulate accurate coordinates, broadbandphotometry, and narrowband fluxes for each source.
