NGC 1068

Source Name:NGC 1068

Type Seyfert 2/ Starburst

Source Parameters

Position: RA = 40.66962153 deg, Dec:-0.01329436 deg

Zenith = 29-70 deg

Cycle I

Analysis by Sweta Menon(sweta.menon@inaf.it)

Data from /fefs/aswg/data/real/DL1/YYYYMMDD/v0.10/tailcut84

MC files : dec_min_413

Energy threshold is quite high(~ 500 GeV) if I include all the data. So as balance between including as much events as possible, I am doing my analysis with a zenith cut of 50 deg, with a threshold of about 180 GeV. ~ 70% of events and observation time of total "good" data taken.

Low Zenith

Zenith < 50 deg
