Dear LHAPDF user,

This is to advise you that the following changes/additions have been
made to the PDF sets available following the release of version 5.8.4.

1)  New versions of:
CT10as.LHgrid
CT10was.LHgrid
These replace the originals which had a bug causing them to be unusable.
Note also that the descriptions in all the CT10 files have been updated.

2) New sets:
CT10f3.LHgrid   (set # 10980)
CT10f4.LHgrid   (set # 10981)
CT10wf3.LHgrid  (set # 10982)
CT10wf4.LHgrid  (set # 10983)
These are the fixed 3 and 4 flavour versions of the CT10 sets..

3) New versions of:
NNPDF20_1000.LHgrid
NNPDF20_100.LHgrid
NNPDF20_as_0114_100.LHgrid
to
NNPDF20_as_0124_100.LHgrid
These have corrected values of Lambda4 and Lambda5.

4) New sets:
NNPDF20_heraold_100.LHgrid    (101 members set #s 192000-192100)
NNPDF20_dis_100.LHgrid        (101 members set #s 192200-192300)
NNPDF20_dis+dy_100.LHgrid     (101 members set #s 192400-192500)
NNPDF20_dis+jet_100.LHgrid    (101 members set #s 192600-192700)
These are fits to restricted data sets.

All of these are available from the LHAPDF website

http:http://projects.hepforge.org/lhapdf/pdfsets

or using the bin/lhapdf-getdata script.

Note that all the above will work with version 5.8.4 providing only the
names are used to initialize the sets.  However if you wish to use the
numbers (ie lhaglue/pdflib method) then you will need to update your
lhapdf installation with the patches available on the web site
(lhaglue.f and PDFsets.index).

Any problems, as usual, let me know.

Best regards,
Mike Whalley
