For the records, I require(d) a bunch of Landsat scene center coordinates. Yes, in decimal degrees to feed the i.atcorr module. But, it took me a while, to find it (-g). I was sure I have "grepped" decimal degrees from a grass- module before -- couldn't recall, however, which one. Personally a I would prefer a (slightly) different description for the switch, or, at the very least, some additional note in the manual. Thank you Glynn, Nikos
