ReserveIsolatedStarsTask¶
ReserveIsolatedStarsTask is a simple task to generate a consistent selection of reserved stars.
Processing summary¶
ReserveIsolatedStarsTask uses a hashed string to generate a random seed to select a random subset of the total number of stars.
The hash is generated from the lower 32 bits of the SHA-256 hash of a combination of the configured reserve_name and an optional extra string.
In this way, consistent reserve selections can be done based on human-readable names, bands, etc, rather than relying on hard-to-remember numbers.
The return value is a boolean array of the desired length, with reserve_fraction of the array set to True.
