All sky mc bllac

All Sky MC simulation data for BL Lac analysis[edit]
Do we need to apply NSB tuning?[edit]
Probably yes. It is because NSB level is 1.3-1.4 x dark NSB in BL Lac FoV due to the low galactic latitude (-10.44 degree)
How much do we need to tune?[edit]

Which MC is proper for BL Lac analysis?[edit]
dec_3476 and dec_4822 is the closest nodes to the BL Lac path.
How much does NSB tuning affect the analysis?[edit]
You can see some differences below a few hundreds of GeV on intensity distribution. A ratio of surviving events after image cleaning is also different (~5% below 100 GeV).
