# Regular Meeting (2020.4.20)
# Problems about report
## 1. Density about CDC
If each layers(SL1~SL8) keeps 160's sensors,
does a higher layers reduce the density of the sensor?
(Because the circumferenc is increased)
## 2. Why innter(SL0) count of sensors != outer(SL1~SL8)

## 3. About hough voting
