Source Notes:

Source position and its uncertainty:
- no information available
- the source position provided by NED is used

From Mariotti et al.(2010):
- NGC 1275 is the central radio galaxy of the Perseus cluster of galaxies
- No signal is detected above 400 GeV
- The VHE detection happened during a period of increased high
gamma-ray activity of NGC 1275, as reported in July 2010
by the Fermi/LAT collaboration, ATel 2737, and continuing until
October, according to an analysis of public Fermi/LAT data.

Spectral Information:
From Aleksic et al. (2011):
- Spectral index: 4.1 +/- 0.7(stat) +/- 0.3(syst)
- Flux: 2.5% +/- 0.4(stat) Crab
From Aleksic et al. (2011):
- Spectral index: about 4 below 600 GeV

Distance:
- The redshift of z = 0.017559 +/- 0.000037 quoted here is from Strauss et al. (1992)

Classification:

From Brown & Adams (2011):
- "Classified as a Fanaroff–Riley type I (FR I) radio galaxy, NGC 1275
is extremely radio bright, exhibiting clear structure of a compact central
source and an extended jet (e.g. Vermeulen et al. 1994; Asada et al. 2006)."

From Aleksic et al. (2014):
- "In radio, the emission is dominated by a very bright compact source
(3C 84) at the center of the galaxy. The core-dominated morphology
with asymmetrical jets at both kpc (Pedlar et al. 1990) and pc scales
(Asada et al. 2006) looks like a FanaroffRiley type I (FR I) radio
galaxy with a jet axis relatively close to the line of sight."
