	NOTE : Working accuracy


	The  working  accuracy  was  obtained by  calculating  the effective 
	beam stopping coefficient via ADAS310 using three different ion/atom
	collision cross-section databases,  i.e. ADF02  type files. An ADF02
	type file contains  indexed entries  of key ion/atom reaction cross-
	sections with  H and other species. The first detailed assessment of 
	ion/atom cross section data for beam stopping was completed  at  JET 
	in 1989 ( small corrections and extensions were made to the file up
	to 1993 ) . This file was originally saved /adas/adf02/ionatom/h.dat 
	but was later reformatted and saved as /adf02/sia#h/sia#h_rfm#h.dat. 
	Guided by  experimental  observations at JET  and the  lack  of high 
	quality CCAO calculations when the  JET 1989  data set was compiled, 
	the cross-sections of the JET 1989  data  set  was considered to be 
	some what under-estimated.  A  new review of all  ion/atom collision 
	data was carried out. The only substantial  contribution  found  was 
	that of the  close  coupled  atomic  orbital (CCAO)  calculations of 
	Toshima & Tawara [1]. This  data  together  with the data of Janev & 
	Smith [2]  was  used  to  create  yet  another  ADF02  type  file,
	sia#h_tosh#h.dat.However,the CCAO calculations of Toshima & Tawara[1] 
	only include states up to n=4 and so some over-estimation is present,
	particularly for ion  impact  ionisation from n=3 and n=4 shell. The 
	cross-sections contained in this  data set are considered to be over-
	estimated.  A  comparative  data  set  was  constructed  which  was a 
	compromise between both data sets,this is what is called the JET 1997
	review data set, sia#h_j97#h.dat. The  JET  1997  review  data is the 
	preferred data set. The  working  accuracy  was  obtained  by running 
	ADAS310 using  each data set.  The  results  from using  the JET 1997 
	review data  is  taken  as  the most accurate  value.The results from 
	using the JET 1989  data  set  are  used to obtain a lower  limit.The 
	results from the Toshima & Tawara data set are used to obtain an upper
	limit. Using the values of  the  lower  and  upper limit a percentage 
	difference is used to describe the MAXIMUM deviation from the results
	obtained using the JET 1997 review data.
