Correcting offset in HiCO geolocation

Hi, an earlier post in this forum explained the reason for some HiCO images not being geolocated quite correctly. I noticed when viewing a cloud free image in SeaDAS 7.0.2 that when I enabled the coastal mask, that it did not line up correctly with the image (in this case quite a few km off). But af...
