Table 6: Comparison of the GENIE and ALADDIN performance expressed in detectable exozodiacal disc densities as compared to the solar zodiacal disc. Four different levels of uncertainty have been assumed on the angular diameter of the target stars. The simulations are performed in the L band, which extends from 3.5 to 4.1 $\mu$ m in the case of GENIE and from 3.1 to 4.1 $\mu$ m in the case of ALADDIN. An integration time of 30 min is assumed in all cases.
