6.2 Setting Parameters

All keyword here are parameters. This means that they are allowed only in the first part of an input script, i.e. before the objects_and_labels command (if there is one).

• Essential parameters: What probably all your input scripts will need.
• Switching things on or off: How to remove e.g. all nebulae easily.
• Filtering by brightness: Removing too faint objects.
• Colour and line style and other layout: Miscellaneous layout.
• Implementing a global style: Global PP3 file and LaTeX preamble.
• Penalties: Finetune the overlap avoiding algorithm.
• Filenames: Setting filenames for database files.
