Table information for 'ohmaser.monitor'


Table Description: Table of measurements included from monitoring programs.

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: A all-sky compilation of galactic stellar sources observed for OH maser emission in the transitions at 1612, 1665, and 1667 MHz. The database contains OH maser observations selected from the literature . These observations belong to more than 6000 different objects. The database consists of three tables: The main table ("masers"), interferometric followup observations ("maps") and monitoring programs ("monitor").
