Table of Contents

**out=***out_file*- Write a
binary table
**OsipkovMerrittModel**to*out_file*. No default.

**w0=***dimensionless central potential*- This parameter defines the starting
point for the integration of the corresponding differential equations (see
King (1966) or Binney & Tremaine (1987)). Default:
**-1.0**.

**mass=***total mass of system*- Used for calculating the real values from the
previously computed unscaled model. Default:
**1.0**.

**rc=***core radius*- The core radius is the scaling parameter for the radius.
It is defined as radius at which the surface brightness falls down to half
of its initial value. Default:
**1.0**

**nsteps=***number of steps*- Number of steps to tabulate. Default: 101

**epsilon=***accuracy for integration*- Epsilon is used to define the precision
of the numerical integration Default: 1e-6

**tab=***table filename*- If a filename given, the calculated values will also
be tabulated in an ASCII-file. If no filename is given, no table is output.
Default: no table file.

**g=***gravitational constant*- to create models with physical quantities, set
this constant. Default: not used. (as it should be)
