INTEGRAL Source Naming Convention

The INTEGRAL source naming convention was accepted by the International Astronomical Union (IAU) on 13 March 2001.

The convention is: IGR JHHMMm+- DDMM

In this convention the J2000 coordinates are truncated, not rounded to fit. HHMMm are the hours of right ascension (HH) followed by minutes of right ascension with one decimal (MMm). DDMM are degrees (DD) plus arc-minutes (MM) of declination.

For example, Sirius has the following 2000.0 coordinates: RA = 06h45m08.9173s, DEC = -16o42'58.017" . In the present case, the naming convention would give IGR J06451-1642.

INTEGRAL is officially registered with the IAU and the Strasbourg astronomical Data Center (CDS); for more information see the CDS web page.
