J/ApJ/670/346   M giant stars in the Sagittarius dwarf galaxy. V.  (Chou+, 2007)

A 2MASS all-sky view of the Sagittarius dwarf galaxy. V. Variation of the metallicity distribution function along the Sagittarius stream. Chou M.-Y., Majewski S.R., Cunha K., Smith V.V., Patterson R.J., Martinez-Delgado D., Law D.R., Crane J.D., Munoz R.R., Garcia Lopez R., Geisler D., Skrutskie M.F. <Astrophys.

ADC_Keywords: Stars, giant ; Stars, M-type ; Spectroscopy ; Equivalent widths Keywords: galaxies: evolution - galaxies: interactions - Galaxy: halo - Local Group Abstract: We present reliable measurements of the metallicity distribution function (MDF) at different points along the tidal stream of the Sagittarius (Sgr) dwarf spheroidal (dSph) galaxy, based on high-resolution, echelle spectroscopy of candidate M giant members of the Sgr system.

Note (1): "0.0(-)" means that our iterative procedure was converging on a model atmosphere with logg<0, whereas the Kurucz (1994, CD-ROM 19) model atmosphere grids do not go below logg=0. In these cases, we have adopted the logg=0 atmosphere.
Global notes: Note (G1): Samples as follows: 1 = Sgr Core 2 = Sgr North Leading Arm--Best Subsample 3 = Sgr North Leading Arm--Less Certain Subsample 4 = Sgr South Leading Arm 5 = NGC Group 6 = Calibration Stars
