This FR Al.1 terminator was acquired 13.6 sec before tim2orbit
sunset.  The 30 sec exposure would have extended through sunset.
The bottom panel is the raw data, clipped at 150 DN.  The
half-image was decompressed and de_spiked

and the middle panel displays
 
     tvscl,img2-big_smooth(img2,15)>(-10)<20
 
while the top panel is the smoothed image
 
	    tvscl,big_smooth(img2,15),0,256
 
The grill pattern and the wrinkles are evident.
