The measurements were made at the US Naval Observatory Flagstaff Station between 1989 and 2017, and the average uncertainty in the parallax values is 0.6mas. We find good agreement with Gaia Data Release 2 measurements for the stars in common, although there may be a small systematic offset similar to what has been found by other investigators. The sample is matched to catalogs and the literature to create a photometric data set that spans the ultraviolet to the mid-infrared. New mid-infrared photometry is obtained for 19 stars from archived Spitzer mosaics. New optical spectroscopy is presented for seven systems and additional spectra were obtained from the literature. We identify a subsample of 179 white dwarfs (WDs) at distances of 25-200pc. Their spectral energy distributions (SEDs) are analyzed using model atmospheres. The models reproduce the entire flux-calibrated SED very well and provide the atmospheric chemical composition, temperature, surface gravity, mass, and cooling age of each WD. Twenty-six WDs are newly classified, and 12 systems are presented as candidate unresolved binaries. We confirm one WD+red dwarf system and identify two WDs as candidate dust disk systems. Twelve old and high-velocity systems are identified as candidate thick disk or halo objects. The WDs in the sample generally have Galactic disk-like ages of <8Gyr and masses close to the canonical 0.6M_{sun}_.2018ApJS..239...26Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/239/26CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/284 : The USNO-B1.0 Catalog (Monet+ 2003)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)I/289 : UCAC2 Catalogue (Zacharias+ 2004)II/319 : UKIDSS-DR9 LAS, GCS and DXS Surveys (Lawrence+ 2012)II/359 : The VISTA Hemisphere Survey (VHS) catalog DR4.1 (McMahon+, 2013)II/328 : AllWISE Data Release (Cutri+ 2013)V/147 : The SDSS Photometric Catalogue, Release 12 (Alam+, 2015)II/349 : The Pan-STARRS release 1 (PS1) Survey - DR1 (Chambers+, 2016)II/343 : VIKING catalogue data release 2 (Edge+, 2016)I/345 : Gaia DR2 (Gaia Collaboration, 2018)J/PASP/109/849 : Probing the LHS Catalog (Gizis+ 1997)J/ApJS/133/413 : BVRIJHK photometry of cool white dwarfs (Bergeron+, 2001)J/ApJ/586/1356 : White dwarfs with cool companions (Wachter+, 2003)J/ApJS/156/47 : DA WDs from the Palomar Green Survey (Liebert+, 2005)J/PASP/117/676 : LHS faint proper-motion stars (Reid+, 2005)J/ApJS/167/40 : SDSS4 confirmed white dwarfs catalog (Eisenstein+, 2006)J/AJ/132/1221 : VJHK and SDSS photometry of DA white dwarfs (Holberg+, 2006)J/MNRAS/373/781 : JHK photometry of faint standard stars (Leggett+, 2006)J/ApJ/663/1291 : DZ stars in SDSS DR4 (Dufour+, 2007)J/AJ/134/26 : Binaries with white dwarf in 2MASS (Hoard+, 2007)J/AJ/134/252 : New nearby white dwarf systems (Subasavage+, 2007)J/ApJS/190/77 : Detailed analysis of cool WDs in the SDSS (Kilic+, 2010)J/ApJS/190/100 : NIR proper motion survey using 2MASS (Kirkpatrick+, 2010)J/ApJS/197/38 : The WIRED survey.
