CDROM/AJ/V110/P1774 K Giants in Baade's Window (Terndrup+ 1995) ================================================================================ K Giants in Baade's Window. I. Velocity and Line-Strength Measurements D. M. Terndrup, Elaine M. Sadler, R. Michael Rich <1995, AJ, 110, 1774> =1995AJ....110.1774T ================================================================================ Abstract: This is the first in a series of papers in which we analyze medium-resolution spectra of over 400 K and M giants in Baade's Window. Our sample was selected from the proper motion study of Spaenhauer et al. [AJ, 103, 297 (1992)]. We have measured radial velocities for most of the sample, as well as line-strength indices on the system of Faber et al. [ApJS, 57, 711 (1985)]. We analyze the random and systematic errors in velocities and line strengths, and show that the bright (V < 16.0) stars in our sample are predominantly foreground disk stars along the line of sight toward Baade's Window. We find that most of the bulge K giants have stronger Mg absorption at a given color than do stars in the solar neighborhood. If the K giants in our sample are moderately old, we suggest that on average they may have [Mg/Fe] approximately +0.3, consistent with the results of recent high-resolution spectroscopy in Baade's Window.

Rich's spectra were taken either at "low" resolution (4.5 A; similar to the author's AAT and CTIO spectra) or "high" resolution (2.7 A). Rich estimates velocity errors of 34 km/s (L) and 15 km/s (H) for the two samples. -------------------------------------------------------------------------------- Byte-by-byte Description of file: table7.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 5 A5 --- Star Star identification 6-11 F6.2 --- Fe5270 []?
