The absorption band center of visible and near infrared reflectance spectra is a key spectral parameter for lunar mineralogical studies, especially for the mafi
We present stellar parameters and abundances of 15 elements(Na,Mg,Al,Si,Ca,Sc,Ti,V,Cr,Mn,Fe,Ni,Cu,Y and Ba)for 23 field RR Lyrae variables based on high-resolut
