Class Starfield

Object

hirondelle.starfield.physics.Starfield

public final class Starfield
extends Object

Perform the desired calculation and generate an image.

Scans the star catalog, parses each line into a Star, applies a boost to get a BoostedStar, which is then added to the result. Any files in the star catalog directory whose name ends in '.ignore' are ignored. (This is intended as a convenience when testing.)

Method Detail

calculate

public StarfieldStats calculate()

Calculate high-level statistics for the starfield using the given input parameters, and output an image.

The statistics returned are:

• the number of stars in the calculation (visible and invisible)
• the number of visible stars for the current boost, above the given limiting magnitude
• the total brightness index of all the visible stars. Here, each 0-magnitude star contributes a value of 1 to the brightness index, for example.

If the output file is null, then no image file will be created.
