As you guys may know computer science icon Jim Gray disappeared at sea
last Sunday, and the Coast Guard has not been able to find any trace. It
is a complete mystery.
We have started an effort to find him by getting access to satellite

has worked deep into the night to make this happen.
We have however hit an obstacle to which we have no answer: the image
format is 16 bit panchromatic with on 11 bits used for data (tiff). If
