With AOT you mean aerosol optical thickness right? This is user input to i.atcorr. There are various sources for AOT at 550nm, e.g. MODIS. Anyway, it is probably much easier to to write your own routine to read the AERONET file and get the corresponding formula for AOT than to fight with 51821 lines of Fortran source code that is numerically unstable. Maybe I can help with getting AOT at 550nm from an AERONET file avoiding the Fortran version of 6S.
