Sumario:<HTML> <HEAD> <h2>Abstract</h2> </HEAD> <P> <BODY> <P> In the optical monitoring systems suggested to control the geometry of tracking spectrometers, light beams serve as reference frames for the measurement of the tracking chamber displacements and deformations. It is shown that air temperature gradients can induce systematic errors which considerably exceed the intrinsic resolution of the monitoring system. </BODY> </HTML>
