In converting DN values to radiance as well as reflectance, do we use the same equations in raw satellite imagery for pansharpened products? I saw this DigitalGlobe technical note for DN to radiance conversion where "the information applies to all Quickbird products EXCEPT pansharpened" imagery. So may I know then how pansharpened imagery are atmospherically corrected, i.e from DN to radiance to reflectance?
