 | The Y-axis is in Ohms, which corresponds to displacement of the graphite rod in the sensor. |
| The thick main line is due to microseism activity. |
| The overall upward trend is due to temperature variations. |
| The sharp shifts at approximately 07:20 and 15:30 are due to the car nearest the sensor leaving and returning. |
| Other cars in the garage are responsible for the other shifts |
