As I recall, the order is reverse between Photosphere and hdrgen. If the R response is from your Photosphere file is 7.135383e-03,-3.556814e-02,2.441168e+00,-5.786777e+00,4.462320e+00
it should be a "mirror image" in hdrgen: 4.462320e+00, -5.786777e+00, 2.441168e+00, -3.556814e-02, 7.135383e-03 Mehlika On Mon, 13 May 2013, Michael Martinez wrote: > The rsp looks good - nice and smooth, which makes sense as Photosphere seems > to have no trouble with these values.
