In addition, Mn abundance determinations have been made for a comparable number of halo field and disk stars possessing an overlapping range of metallicities and stellar parameters. Our primary data set was comprised of high-resolution spectra previously acquired at the McDonald, Lick, and Keck Observatories. To enlarge our data pool, we acquired globular and open cluster spectra from several other investigators. Data were analyzed using synthetic spectra of the 6000Å Mn I triplet. Hyperfine structure parameters were included in the synthetic spectra computations. Description: Three facilities were used for the Lick-Texas Group (LTG) observations: the KeckI 10.0m telescope equipped with the High Resolution Echelle Spectrometer (HIRES), the Lick 3.0m telescope equipped with the Hamilton spectrograph, and the McDonald 2.7m telescope equipped with the 2d-coude spectrograph. The remainder of the globular and open cluster spectra were obtained from several external sources, detailed in Table 12. File Summary:

Note (1): Note that the number of program stars does not always equal those found in the original paper. In some cases the S/N was too low in a specified wavelength range to obtain a [Mn/Fe] ratio. Note (2): Instrument used, defined as follows: ESO (40) = ESO 3.6 m telescope CASPEC spectrograph with R∼40000; Keck (34) = KeckI 10.0m telescope HIRES spectrograph with R∼34000; Keck (45) = KeckI 10.0m telescope HIRES spectrograph with R∼45000; Lick (30) = pre-1995 configuration of Lick 3.0m telescope Hamilton echelle with R∼30000; Lick (50) = current configuration of Lick 3.0m telescope Hamilton echelle with R∼50000; McD (30,60) = McDonald 2.7m telescope 2d-coude with R∼30000 or 60000; CTIO (24) = CTIO 4.0m telescope echelle spectrograph with R∼24000; CTIO (30) = CTIO 4.0m telescope echelle spectrograph with R∼30000; VLT (40:60) = VLT UVES spectrograph with R∼40000 or 60000; APO (34) = APO 3.5m telescope echelle spectrograph with R∼34000. Note (3): Flag on S/N gives the wavelength, defined as follows: A = 6300Å; B = 6350Å; C = 6363Å; D = 6460Å; E = 4100Å; F = 5500Å. G = 5865Å; H = 6700Å; I = 7500Å.

Note (1): Field stars from the Fulbright (2000, Cat. J/AJ/120/1841) survey (labeled as JF) have Hipparcos identifications (table 3 only). Similarly, target stars of the Simmerer et al. (2004, Cat. J/ApJ/617/1091) survey (designated as JS) have Henry Draper identifications unless otherwise indicated.
