How can I query the calibrator database that ALMA uses?

The ALMA calibrator database can be directly queried through a web form at http://almascience.org/sc/.

Alternatively, you can query the ALMA calibrator database from the OT in this way:

  • Open up the OT and create a Science Goal (or use an existing Science Goal)
  • Go to the "Calibration Setup" of the Science Goal 
  • Select "User Defined Calibration"
  • Select "Add fixed calibrator" and pick e.g. bandpass or phase


This brings another interface.

  • Select "Sideral Target"
  • Click "Select from Source Catalog" 


This brings up a query interface you can use to find calibrators and their fluxes with dates.
