Notes. ^(a) Cepheid coordinates: units of right ascension are hours, minutes, and seconds; units of declination are degrees, arcminutes, and arcseconds. ^(b) Reddening according to Fernie et al. (1995). ^(c) Mean NIR magnitudes. ^(d) Number of spectra collected with FEROS at the 2.2 m MPG/ESO telescope. ^(e) Mean radial velocity and velocity amplitude (km s^-1).
