Grid Downloads
Here you can download grids for APPLgrid version APPLVER for fast cross section evaluation.
These grids are fully differential and should require no additional scaling. Each
should include the non-perturbative (and any additional) bin-by-bin corrections or K-factors,
the application of which is discussed in the relevant papers - see the
Documentation page for more information.
Please note that these grids should be based on the grids that were used for the
relevant papers, and were not necessarily created by the the applgrid authors.
-In the future, it is hoped that grids will be distributed using the ploughshare project.
+These grids are here for historical purposes, now grids are distributed from the
+ ploughshare project.

Code Download
Various code for download is available:
- You can download the latest version (APPLVER) of the standard APPLgrid convolution code
here
.
- If you wish to use arbitrary factorisation scale variation,
you will need to have hoppet installed first, which you can
download from
here
.
- There are some simple examples which you can download from
here .
These examples requires that you have LHAPDF installed
which you can find
here
.
- In addition, APPLgrid uses root files for storage, although not internally, so you should also install root
which you can find
here
.
Calculation Code
If you wish to generate your own grids, we currently have NLOjet++ available for jet production at NLO and MCFM for most other processes.
- For NLOjet++ we have our own custom version 4.0.1 which can be downloaded from
here .
This requires the nlojet pdf module that you can download from
here .
The user module
can be downloaded from
here
- For MCFM, you should download the standard version of MCFM (6.7 or later).
To link with applgrid, before installing MCFM, you should download and install the
mcfm-bridge
code, which you install with the usual ./configure ; make ; make install etc.
After running this you will need to patch the standard installation using the
patch file which you should untar in
the MCFM base directory and then remove the file
src/User/gridwrap.f
then just build using make. To link with applgrid, before running make, you should set the LDFLAGS
enviroment variable to the output from
mcfm-bridge --ldflags
NB: you should not use the standard install script that comes with MCFM.
Other interfaces are being developed and will be released when available.
