H2O Masers

Here we present data on the 325 H2O masers detected by the RAMPS pilot survey. The table below shows the Galactic coordinates, error on the coordinates, the velocity and intensity of the brightest channel, and the associated environment for each maser. The maser positions given are the integrated intensity weighted positions, while the error on the position is a combination of the error on the integrated intensity and the typical pointing error, which always dominates. We determined the associated environment through the presence or absence of NH3 or a bright, reddish star in the GLIMPSE/MIPSGAL data. If we found NH3 emission coincident with the H2O maser position, we inferred that the maser was associated with a star-forming region (SFR). If there was no NH3 emission, we searched the GLIMPSE/MIPSGAL map for a 24 µm bright star. If this was the case, we inferred that the maser was associated with an evolved AGB star. If neither case was satisfied, the maser was labeled an unknown association.
