#### Mars

The brightness temperature of Mars depends on the frequency and on the time of the observations. E. Lellouch et al. in Observatoire de Paris developped an implementation of a full physical and radiative transfer model to compute the surface-averaged brightness temperature of Mars.

Such a tool is used by some observers of the IRAM community, especially for 30m observations. Lellouch et al. agreed to provide us with the Mars model sources so that we can directly use their model in ASTRO. We are now in the process of finding the best way to implement this.
