The minimal required total oscillation range as a function of the starting
spindle angle will be displayed in a PostScript file. The name of this
file is specified by the * PSFIle* command, the default
is ** strategy.ps**. The PostScript file contains a number of coloured figures,
displaying the minimal required total oscillation range as a function
of the starting spindle angle for the default and/or desired completeness values.
The completeness is defined as the percentage of unique reflections that can be recorded.
If the desired completeness is higher than the maximum completeness obtained
by rotation of the crystal around the spindle axis for 360 degrees, the program
will use the maximum completeness rather than the desired one.

Figure shows one page of the PostScript file.

**Figure:** PostScript figure produced by * STRATEGY*

The figure is composed of a collection red vectors starting from the origin and representing the total minimal oscillation range (length of the vector) for a certain starting spindle angle (angle that the vector make with the horizontal axis). Seven black (dashed) circles are used to indicate the total oscillation range of 180, 135, 120, 90, 60, 45 and 30 degrees respectively. In green, four values of the starting spindle angle are given: 0, 90, 180 and 270 degrees.

The red patterns will be centrosymmetric if the * ANOMalous* option
has ** not** been used: Friedel's law can then be applied.
The unique local minima of each figure
will be listed in the log file produced by * STRATEGY*.
