ALMA Data

The ALMA Science Archive

The ALMA Science Archive holds all public and proprietary science data. The Archive provides a form-based query tool to the data and allows for anonymous or authenticated download.

The ALMA Calibrator Source Catalogue

A web-based user interface to the calibrator database is provided through the  Calibrator Catalogue link in the left side-bar. The data comprise ALMA calibrator measurements of the flux density for sources drawn from seed catalogues such as ATCA, SMA and VLA, and use updated coordinates from VLBI (ICRS). Details on the Calibrator Source Catalogue can be found in Fomalont, E., et al., 2014, "The Calibration of ALMA using Radio Sources', The Messenger, 155, 19", and the ALMA Technical Handbook also describes principles of the calibrator selection during observation.

Science Verification Data

In addition to the archive, there are several datasets available as Science Verification data. These observations are performed in order to demonstrate the early capabilities of ALMA. Access to the data sets are through the link Science Verification in the left side-bar. Information about planned Science Verification observations are also presented. Publications making use of ALMA Science Verification data must include a statement in the acknowledgement that is similar to the one for regular data (see below). The Science Verification acknowledgement can be found under the Science Verification link in the left side-bar.

Using ALMA data for publication

Publications making use of ALMA data must include the following statement in the acknowledgement:

This paper makes use of the following ALMA data: ADS/JAO.ALMA#2011.0.01234.S . ALMA is a partnership of ESO (representing its member states), NSF (USA) and NINS (Japan), together with NRC (Canada), NSC and ASIAA (Taiwan), and KASI (Republic of Korea), in cooperation with the Republic of Chile. The Joint ALMA Observatory is operated by ESO, AUI/NRAO and NAOJ."

Please substitute the place-holder project code 2011.0.01234.S with the code(s) of the data used.

In addition, publications from NA authors must include the standard NRAO acknowledgement:
"The National Radio Astronomy Observatory is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc." .
