J/MNRAS/246/54 Late-type giants in Baade's window (Sharples+ 1990)
================================================================================
Kinematics of the late M-giants in Baade's window
Sharples R., Walker A., Cropper M.
<Mon. Not. R. Astron. Soc. 246, 54 (1990)>
=1990MNRAS.246...54S
================================================================================
ADC_Keywords: Stars, late-type ; Radial velocities ; Photometry, infrared
Description:
Radial velocities have been measured for an unbiased sample of 239
late-type M giants in the b=-4{deg} galactic bulge window (Baade's
window). The radial velocities were acquired at the AAT Observatory.

--------------------------------------------------------------------------------
Note on TiO: the TiO line strength is defined as 2.5log(F1/F2),
where F1 is the integrated flux over the rest-wavelength range
837-842nm and F2 is evaluated over the range 844-849nm.
Note on CaII: method described by Armandroff & Zinn (1988AJ.....96...92A)
Note on Mbol: assuming Ro = 7.8 kpc from Frogel & Whitford (1987ApJ...320..199F)
