In this work, we present a catalog of DA white dwarfs (DAWDs) from the entire pilot survey. We outline a new algorithm for the selection of white dwarfs (WDs) by fitting Sersic profiles to the Balmer H{beta}, H{gamma}, and H{delta} lines of the spectra, and calculating the equivalent width of the CaII K line. Two thousand nine hundred sixty-four candidates are selected by constraining the fitting parameters and the equivalent width of the CaII K line. All the spectra of candidates are visually inspected. We identify 230 DAWDs (59 of which are already included in the Villanova and SDSS WD catalogs), 20 of which are DAWDs with non-degenerate companions. In addition, 128 candidates are classified as DAWDs/subdwarfs, which means the classifications are ambiguous. The result is consistent with the expected DAWD number estimated based on the LEGUE target selection algorithm.2013AJ....146...34Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/146/34CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/139 : The SDSS Photometric Catalog, Release 9 (Adelman-McCarthy+, 2012)I/322 : UCAC4 Catalogue (Zacharias+, 2012)III/235 : Spectroscopically Identified White Dwarfs (McCook+, 2008)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)II/207 : Palomar-Green catalog UV-excess stellar objects (Green+ 1986)J/AJ/145/159 : LAMOST.
