Keck HIRES spectra of TYC 4144 329 2 (two individual exposures averaged together) and main-sequence, F-type stars not known to have any orbiting dust (the spectrum of HIP 106985 comes from the ELODIE archive; Moultaka et al. 2004). Comparison of temperature-sensitive absorption lines indicates that the temperature class of TYC 4144 329 2 is somewhere between an A7 star ( V − K = 0.62) and an F5 star ( V − K = 1.042). The slanted lines are added to help guide the eye and have their slopes fixed at the slope value determined from comparing the line strength ratios of the Fe ii and Fe i absorption lines of TYC 4144 329 2. The best match appears to be around an F2 star ( V − K = 0.85). Wavelengths in this figure are plotted in the heliocentric air scale. The comparison spectra have been shifted to TYC 4144 329 2's heliocentric reference frame.
