GAMA Queries (astroquery.gama)

Getting started

This module can be used to query the GAMA (Galaxy And Mass Assembly) survey, second data release (DR2). Currently queries must be formulated in SQL. If successful, the results are returned as a Table.

SQL Queries

This sends an SQL query, passed as a string, to the GAMA server and returns a Table. For example, to return basic information on the first 100 spectroscopic objects in the database:

>>> from astroquery.gama import GAMA
>>> result = GAMA.query_sql('SELECT * FROM SpecAll LIMIT 100')
