Hello,

I am trying to write a NXxas file following the Application definition from the  
the "NeXus Reference" document, and I have two questions/doubts about it:

a) The monochromator energy appears as NX_CHAR type (and this is also the case 
for the NXxasproc application definition). I would expect it to be NX_FLOAT 
instead (that would be consistent with the NXmonochromator class definition). I 
see that the source XML file [1] does not include any explicit type for this 
field, so I wonder if it might be a mistake in the definition (which should be 
explicit) or in the script that generates the NeXus Reference (which perhaps 
defaults to NX_CHAR if no explicit type is defined?).

b) The link in the NXdata group to the absorbed beam is made to 
"/entry/instrument/absorbed_beam"  (which is a NXdetector group). I would 
expect it to be to "/entry/instrument/absorbed_beam/data"  (an NXfield)

Can somebody please clarify these things?

Cheers!

Carlos
