The minimum value for any channel on MSG-1 is currently 51
Looking closely at the 10 bit histogram on current HRIT images I
cannot detect this lower limit anymore. (it was there on the
image processing system IIPS)
The 51 offset is still there. You will find that the look-at-space
parts of the image are no longer set to 51 (but zero as I recall).
The 51 is still defined in the prolog.

Note that min150 is the Min value upperlimit, not the value I read
on the histogram !

I'll increase the lower limit maximum, then up to 240 or so, and
reduce the upper limit minimum for the next (beta) version.
