What's going on here:

IDL> help,slice
SLICE LONG = Array(64, 64)
IDL> print,!d.n_colors
256
IDL> print,max(slice)
395862411
IDL> bslice = bytscl(slice)
IDL> print,max(bslice)
255
IDL> bslice = bytscl(slice,top = 100)
IDL> print,max(bslice)
245

Shouldn't the max of bslice now be 100? Is this a bug in bslice?

Any help would be appreciated.

Thanks,
Phil
