build_catalogue

giant.scripts.build_catalogue:

Build a giant star catalogue file from the UCAC4 star catalogue.

This can be run if for some reason the default catalogue file delivered with GIANT doesn’t meet your needs (i.e. if it doesn’t contain high enough magnitude stars, it doesn’t blend enough stars, or similar). This script does take a while to run so it is usually recommended to use nohup to run in the background.

Usage

usage: build_catalogue [-h] [-f FILE] [-u UCAC_PATH] [-m LIMITING_MAGNITUDE] [-b BLENDING_MAGNITUDE] [-n NUMBER_OF_STARS] [-s LIMITING_SEPARATION]

Named Arguments

The path to the UCAC catalogue if it is not at the default location

-m, --limiting_magnitude

The maximum magnitude to include in the catalogue

Default: 12

-b, --blending_magnitude

The magnitude to try and blend dimmer stars to

Default: 8

-n, --number_of_stars

The number of stars that can be blended to reach the blending magnitude. Set to 0 to turn off blending
