I am using GRASS 6.4.4 for atmospheric correction. Can any one suggest how to add a sensor which needs a new argument for i.atcorr other than arguments mentioned in GRASS GIS manual: i.atcorr.

I have customized a module which required additional information other than existing flags like Opts.icnd. Can I create a new structure variable and give as an argument to i.atcorr?

One more query regarding the number of bands: is there any limitation if more than 7 bands are used while using the same igeom of landsat? I tried to give 30 band image and corresponding RSR in i.wave.cpp.But 6s, but results show that after the 7th band all band have zeros. Can any one suggest to me how to use i.atcorr for more number of bands?
