Water maser spectra of the detected sources. Note that some objects were observed more than once. The x-axis is the velocity with respect to the local standard of rest (kinematical definition) in km s^-1, and the y-axis is flux density in Jansky. The spectra in the left column show the full scale in flux density, and a range of 200 km s^-1 in velocity (except in the case of IRAS 18113−2503, which is shown with a velocity range of 600 km s^-1). The spectra in the right column are the same as the corresponding ones in the left column, but with a restricted scale in flux density and/or velocity, to better show weak or narrow spectral features.
