[Rivet] [HepData] Question about format plain input

[Graeme Watt]

Dear Juan,

The path (e.g. "d01-x01-y01") in the YODA format exported from HepData 
is generated automatically from the table/dataset number (01-03 in your 
example) and the number of the x and y axes within the table (always 01 
for tables with "*data: x : y").  It's been requested in the past to 
allow an option in the HepData input file to allow some override of the 
automatic path names, but I think it would be better to allow some kind 
of "mapping" to be coded within the Rivet analysis between the HepData 
histogram names and the Rivet histogram names, for cases where they 
don't match.  At present, however, you probably need to change your 
Rivet analysis to match the automatic HepData path names.  The only 
alternative rearrangement of your tables I can see, assuming that the pt 
values are common to all three tables, is:

*dataset: pp 13 TeV
*qual: Selection : Inelastic : NSD : SD
*yheader: $number of entries$
*xheader: $pt$
*data: x : y : y : y
     {Data points here}
*dataend:

which would give:

/REF/d01-x01-y01
/REF/d01-x01-y02
/REF/d01-x01-y03

Best regards,
Graeme Watt (HepData)
