-===== Sensors =====
+====== Sensors ======
 Sensors or sensor nodes are invisible objects that can be used to monitor light distributions with a scene without interfering with the rest of the scene or the light modelling. For this, GroIMP provides the //SensorNode// class, a spherical object that can be placed arbitrarily within the scene. To obtain the sensed spectrum, the function //getSensedIrradiance()// for the Twilight and the //getSensedIrradianceMeasurement()// function for the GPUFlux light model needs to be called.
+===== =====
 Note: The size of the sensor node directly correlates with the probability of got hit by a light ray. For a very small sphere the probability to got hit by a light ray is relatively low, so the number of light rays simulated by the light model needs to be much larger to get repayable results. Therefore, better not to use very small sensor nodes.
