Additional file 1 of Evaluation of a method to retrieve temperature and wind velocity profiles of the Venusian nightside mesosphere from mid-infrared CO2 absorption line observed by heterodyne spectroscopy

Additional file 1. Figure S1. Five model spectra including white noise with the RMS of 0.5 erg/s/cm2/sr/cm−1. Other symbols are the same as those in Fig. 1. Figure S2. Standard deviations for the (a) temperature and (b) wind velocity in the retrieval results from the five model spectra shown in Figure S1. Other symbols are the same as those in Fig. 4. Figure S3. Five model spectra including white noise with the RMS of 1.5 erg/s/cm2/sr/cm−1. Other symbols are the same as those in Fig. 1. Figure S4. Standard deviations for the (a) temperature and (b) wind velocity in the retrieval results from the five model spectra shown in Figure S3. Other symbols are the same as those in Fig. 4.
