We used data from 1996 to late 2021, and we describe the differences between early and late data, which hinge upon an update of the beam combiner in 2002. We came across several subcategories of stars of interest: 13 of our stars are promising targets for the Habitable World Observatory and therefore require as much study as possible, and 14 more are asteroseismic targets and have stellar masses after we combined our radii and effective temperatures with frequencies of maximum oscillation power values from the literature. In addition to this, many of the stars here show measurements to the first null in the visibility curve and beyond, which is the gateway to determining second-order effects such as direct measurements of limb darkening. Finally, we consider the stars in the larger context of previous NPOI measurements and find the majority (75%) of the angular diameters in the overall NPOI sample have uncertainties of 2% or less.2025AJ....169..293Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/169/293CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/pastel : The PASTEL catalogue (Soubiran+, 2016-)B/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2020)I/149A : Fifth Fundamental Catalogue (FK5) Part I (Fricke+, 1988)I/175 : Fifth Fundamental Catalogue (FK5) - Extension (Fricke+ 1991)I/284 : The USNO-B1.0 Catalog (Monet+ 2003)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)I/345 : Gaia DR2 (Gaia Collaboration, 2018)I/355 : Gaia DR3 Part 1.
