Abstract (from CDS):

In this paper, we present an online multiwavelength database of water masers in star-forming regions of the Galaxy. The collected data represent ∼95% of all observations of water masers in star-forming regions published since 1989. Nineteen transitions are included, from 22 GHz to 1.88 THz. The MaserDB.net information system provides fast and open access to the collected data, including maser tabular data, spectra, and interferometric maser spot data. The database covers ∼18,700 individual observations and ∼7200 maser detections. The data on the water maser detection are available for ∼2600 sources, and interferometric data are available for ∼560 sources. Statistical analysis of the water masers' data and comparison with other abundant maser species found in star-forming regions (OH and CH3OH of class I and II) show that water masers are the most ubiquitous maser type. Access to the water maser database is available online at https://MaserDB.net. The database can be queried using a web search form or Structured Query Language.
