Hi,

this is a typical data type problem.
By default, read_binary reads byte data. If you have floats or else,
this superimposition would occur (though I always witness it the other
way around, when saving a float declared as byte in IDL and opening the
image in Envi). See the DATA_TYPE keywork for read_binary
