Maserdb is multi-purpose tool for analyzing the maser spectral data in the lines of CH₃OH, H₂O, OH and SiO molecules, collected from the available literature and private sources.

There are several ways to use the MaserDB:

Maser search page Allow to do the maser search by name or coordinates in a single object or list of objects.	Maser objects page Provide the ability to select the maser objects of particular species, enter the SQL queries for source selection, and study the statistical characteristics of maser objects.	User-defined list Tool for maser proposal preparations. Allow synchronizing between the user-defined source list and the maser database to provide the detailed information about previous maser detections and non-detections of any species.
Maser transitions Use this page to review all maser transitions included in the maser database.	Download the data Use this option to have a copy of maser database (in CSV format) on your computer and study it with your own tools.	References Use this options to study the papers included in the maser databse.

There are three possible search modes:

Observations

This mode provide the detailed information about original observations from the papers (without any modification), including single-dish and interferometric data.

Maser groups

In this mode observations are combined into maser groups using DBSCAN method with the minimum distance between observations of 60 arcsec.

Maser variability

Use this page to review the maser variability using the single-dish fluxes at all observed epochs. In this mode observations are combined into maser groups using DBSCAN method with the minimum distance of 10 arcsec between observations.

Warning: Maximum number of rows for the input file is limited to 500 000.

Maser Monitoring Organization - A global community for maser-driven astronomy

The maser monitoring organisation is a global community of astronomers, observers and theorists collaborating to better understand the nature of astrophysical masers, their flaring behavior and their uses as tracers of astrophysical phenomena.
