Unable to download ancillary data
Hi, I'm downloading data from your servers in order to produce daily compositions but today I found that my IP seems to be blocked. Do I have to use bandwidth limitation? Or what are the good practices?
I can access https://oceancolor.gsfc.nasa.gov/ from my computer but not from my server.
Thanks.

Help with Aqua/Terra MODIS RGB 250 m
Hi Norman,
I found the issue. I have to change this line:
echo "P5\n7732 7733\n65535"|cat - nak.dat>$i.16bit.log.pgm
Into this:
echo $'P5\n7732 7733\n65535'|cat - nak.dat>$i.16bit.log.pgm
Now I got some black images but I think this is due coordinates.
