		\texttt{nproc} & 
		The process to be studied is given by
		choosing a process number, according to Table~\ref{nproctable}
		in Appendix~\ref{MCFMprocs}.
		$f(p_i)$ denotes a generic partonic jet. Processes denoted as
		``LO'' may only be calculated in the Born approximation. For photon
		processes, ``NLO+F'' signifies that the calculation may be performed
		both at NLO and also including the effects of photon fragmentation
		and experimental isolation. In contrast, ``NLO'' for a process involving
		photons means that no fragmentation contributions are included and isolation
		is performed according to the procedure of Frixione~\cite{Frixione:1998jh}.	\\
		\texttt{part} &
		This parameter has 5 possible values, described below:
		\begin{itemize}
			\item {\tt lo} (or {\tt lord}).
			The calculation is performed at leading order only.
			\item {\tt virt}.
			Virtual (loop) contributions to the next-to-leading order result are
			calculated (+counterterms to make them finite), including also the
			lowest order contribution.
			\item {\tt real}.
			In addition to the loop diagrams calculated by {\tt virt}, the full
			next-to-leading order results must include contributions from diagrams
			involving real gluon emission (-counterterms to make them finite).
			Note that only the sum of the {\tt real} and the {\tt virt} contributions
			is physical.
			\item {\tt nlo} (or {\tt tota}).
			For simplicity, the {\tt nlo} option simply runs the {\tt virt} and
			{\tt real} real pieces in series before performing a sum to obtain
			the full next-to-leading order result. For photon processes that include fragmentation,
			{\tt nlo} also includes the calculation of the fragmentation ({\tt frag})
			contributions.
			\item {\tt nlocoeff}.
			This computes only the contribution of the NLO coefficient;  it is equivalent
			to running {\tt nlo} and then subtracting the result of {\tt lo}.
			\item {\tt nlodk} (or {\tt todk}).
			Processes 114, 161, 166, 171, 176, 181, 186, 141, 146, 149, 233, 238, 501, 511 only, see 
			sections~\ref{subsec:stop} and
			\ref{subsec:wt} below.
			\item {\tt frag}.
			Processes 280, 285, 290, 295, 300-302, 305-307,  820-823 only, see sections~\ref{subsec:gamgam}, 
			\ref{subsec:wgamma} and
			\ref{subsec:zgamma} below.
			\item {\tt nnlo} (and {\tt nnlocoeff}).
			The computation of the NNLO prediction (or the NNLO coefficient in the
			expansion) is described separately below.
		\end{itemize} \\
		\texttt{runstring} &
		When \MCFM{} is run, it will write output to several files. The
		label {\tt runstring} will be included in the names of these files.
		\\
		\texttt{rundir} &
		Directory for output and snapshot files
		\\
		\texttt{sqrts} & Center of mass energy in GeV. \\
		\texttt{ih1}, \texttt{ih2} &
		The identities of the incoming hadrons
		may be set with these parameters, allowing simulations for both
		$p{\bar p}$ (such as the Tevatron) and $pp$ (such as the LHC). 
		Setting {\tt ih1} equal to ${\tt +1}$ corresponds to
		a proton, whilst ${\tt -1}$ corresponds to an anti-proton. \\
%		Values greater than {\tt 1000d0} represent a nuclear collision,
%		as described in Section~\ref{sec:nucleus}. \\
		\texttt{zerowidth} &
		When set to {\tt .true.} then all vector
		bosons are produced on-shell. This is appropriate for calculations
		of {\it total} cross-sections (such as when using {\tt removebr} equal
		to {\tt .true.}, below). When interested in decay products of the
		bosons this should be set to {\tt .false.}. \\
		\texttt{removebr} &
		When set to {\tt .true.} the branching ratios are 
		removed for unstable particles such as vector bosons or top quarks. See the
		process notes in Section~\ref{sec:specific} below for further details. \\
		\texttt{ewcorr} & 
		Specifies whether or not to compute EW corrections
		for the process.  Default is {\tt none}.  May be set to {\tt exact}
		or {\tt sudakov} for processes {\tt 31} (neutral-current DY),
		{\tt 157} (top-pair production) and {\tt 190} (di-jet production).
		For more details see section~\ref{subsec:EW}.		\\
                {\texttt{vdecayid}}, {\texttt{v34id}}, {\texttt{v56id}} &
		Flags to manually set the decays of vector bosons (34) and
		(56) (experimental, not for general use). \\
