Manual mistake for type _span options
According to the current manual version one has the options "uniform", "cosine", "cosine_ib", "cosine_ob" and "equalarea" for type_span in the paramtetric_geo_file.in file. But "cosine_ib" and "cosine_ob" causing an error as you use "cosineIB" and "cosineOB" internally in the dust solver. This can be observed in file mod_parametric_io.f90. Therefore the manual needs to be changed using the right keywords.
