Dimitri,
Boy all these diffractometers that can't do steps properly! Yes, the "ALT"
format is the right way to read the data. Use "CONST" for the bintyp and
start & average step for BCOF(1) & (2). These are in deg*100. For the data
there are 3 columns. The first is 2-theta*3200, second is intensity & third
is the esd for the intensity.
