[Clas_cascades] Meeting notes July 22

[Zhiwen Zhao]

Hi, Hovanes

Sorry I missed the meeting.
So if you look the raw ST hit, you have correction 15% and if you look the decay 
location, you have correction 30%,  are you gonna use both for final 
corrections? Don't those two conditions have some overlap?
