Extended Groth Strip

The Extended Groth Strip (EGS) is a name given to a survey field that was selected for searches for high-redshift galaxies. Among the surveys using it have been an HST-based survey and AEGIS. The region is rectangular, but with edges not aligned with equatorial coordinates (angled more-or-less 45 degrees, I believe aligned with galactic coordinates). Some discoveries are commonly cited with names using the prefix EGS. Cited:

• 1deg10min × 10min - size.
• 14h19m00s - right ascension.
• +52deg48m00s - declination.

The Extended Groth Strip is an extended version of the Groth Strip, a 140 square arcminute region around coordinates J141700+523000, which was used for the Groth Strip Survey (GSS).
