All Sky MC simulation data for BL Lac analysis
Do we need to apply NSB tuning?
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?

Which MC is proper for BL Lac analysis?
dec_3476 and dec_4822 is the closest nodes to the BL Lac path.
How much does NSB tuning affect the analysis?
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).
