other than those of [@moon1985] are less than the typical measurement errors in those parameters. In § \[subsec:tefflogguncertainties\] we quantify the effects of rotation and rotation correction uncertainty on the final atmospheric parameter estimation, $T_\mathrm{eff}, \log g$.

Calibration and Validation Using the HM98 Catalog
=================================================

In this section we assess the effective temperatures and surface gravities derived from atmospheric models and $uvby\beta$ color grids relative to fundamentally determined temperatures (§ \[subsec:teffvalidation\]) and surface gravities (§ \[subsec:loggvalidation\]).

Effective Temperature {#subsec:teffvalidation}
---------------------

A fundamental determination of $T_\mathrm{eff}$ is possible through an interferometric measurement of the stellar angular diameter and an estimate of the total integrated flux. We gathered 69 stars (listed in Table  \[table:teffcal\]) with fundamental $T_\mathrm{eff}$ measurements from the literature and determine photometric temperatures for these objects from interpolation of $uvby\beta$ photometry in ATLAS9 model grids.

Fundamental $T_\mathrm{eff}$ values were sourced from [@boyajian2013], hereafter B13, and [@napiwotzki1993], hereafter N93. Several stars have multiple interferometric measurements of the stellar radius, and hence multiple fundamental $T_\mathrm{eff}$ determinations. For these stars, identified as those objects with multiple radius references in Table  \[table:teffcal\], the mean $T_\mathrm{eff}$ and standard deviation were taken as the fundamental measurement and standard error. Among the 16 stars with multiple fundamental
