Calibration rows
Each ASIC has (176+2 rows x 192 columns), the last two rows are the calibration rows. These rows are not connected to the sensor and are constructed without a pixel/sensor interface. They will be powered just like any other pixel in the ASIC, therefore, they see similar voltages, noise, etc just like other pixels.
