Search for calibrators
Here you can search for calibrators that you may find useful.
To find calibrators within some distance of some position on the sky:
- Put a J2000 R.A. and Declination into the "Position" box to the right, or the name of a source that can be resolved by Simbad.
- Specify a search radius in degrees in the "Radius" box.
To find calibrators within a bounding box defined by R.A. and Declination ranges:
- Put the low and high J2000 R.A. hours into the "R.A. Range" box to the right, separated by a comma; like "16,20" to search between 16 and 20 hours, or "22,2" to search between 22 and 2 hours.
- Put the low and high J2000 Declinations into the "Dec. Range" box to the right, separated by a comma; like "-20,10" to search between -20° and 10°.
If you wish to restrict the search to bright calibrators, specify your flux density limit and to which band it should apply.
If you wish to restrict the search to calibrators that have a measurement, ensure that the "Measurements" box is ticked. If you also select a band, then only calibrators with a measurement in that band will be returned.
Hit the "Search" button to find a list of matching calibrators, or the "Reset" button to clear the entry boxes to their default values.
