Table 3.2: Impact of the star characteristics on the quality of vertical profiles of local density of O3, NO2, NO3, and H2O; (*) in the validity altitude range: 20 km-50 km for NO2 and 25 km-45 km for NO3(see also Table 1.1 of 1.4.3.3). A star is considered as cold if its effective temperature is lower than 6000 K; a star is considered as dim if its visual magnitude is higher than 2. It is supposed here that only occultations measured in full dark and in straylight illumination conditions are considered.
