H₂O and SiO maser spectra of 169 OH/IR stars simultaneously obtained in the H₂O ﹩{6}_{16}-{5}_{23}﹩ and SiO v = 1, 2, J = 1–0, ²⁹SiO v = 0, J = 1–0 transitions from 2011 November to 2012 July observations. Spectra are arranged in the same order as in the tables, as indicated by the identification number. Intensity is given in units of antenna temperature ﹩{T}_{A}^{* }﹩ (K), and the abscissa is V_LSR (km s⁻¹). The identification number, the source name, the molecule and its transitions, and the date of observation are given in the spectrum of each source. The gray vertical dotted lines indicate the stellar velocity.
