# mn\_fit(1)

Interactive analysis package for fitting data and histograms

## NAME

mn\_fit - Interactive analysis package for fitting data and histograms

## SYNOPSIS

**mn\_fit** \[ *options* \] \[ *macrofile(s)* \]

## DESCRIPTION

**mn\_fit** is a program used to perform a wide variety of mathematical fits and analyses on data or histograms.  It is based on the MINUIT package from CERN, and can be extended by use of the COMIS FORTRAN interpreter.  **mn\_fit** may be started from the command line by specifying one or more macro files to execute, or it may be started with no arguments for immediate user interaction.  Note that if you specify a filename with the **mn\_fit** command, the first line of the file should be blank, or else should specify the screen device.

## OPTIONS

The program recognizes other arguments at the command line, but only the following are relevant on a Linux system.

- **-h, -?**

  Show summary of options.

- **-db**

  Run the binary executable under gdb for debugging purposes.

- **-n** *host*

  Set the display to *host*:0.0 before starting up.  Of course the remote host must have permitted X display access to the machine on which **mn\_fit** is running.  If you are running **mn\_fit** over an SSH connection with X forwarding enabled, you will not need this potentially unsafe option.

- **-r**

  Run the binary executable with ROOT interface.  As ROOT is not (yet) in Debian, this option will not work in the Debian package.

- **-u** *path/to/other/mn\_fit*

  Instead of the binary executable in /usr/lib/mn-fit, start a different program, for instance a user-compiled version.  The program executed will be *path/to/other/mn\_fit*\_x.exe

## FILES

- *higz\_windows.dat*

  Line 10 of this file (if it exists in the current directory) will be used to set the display size.

- *mn\_logon.mnf*

  Commands will be read from this file in the current directory at startup.

- *~/.mn\_fitrc*

  After running any *mn\_logon.mnf* in the current directory, commands will then be read from this file at start-up.

## SEE ALSO

The **mn\_fit** manual is available in the mn-fit-doc package, and at the URL *http://www-zeus.physik.uni-bonn.de/~brock/mn\_fit\_html/mn\_fit.html* . The program also has an extensive online help system.
