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¶
- -f, --file
The file to save the catalogue to
- -u, --ucac_path
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
Default: 4
- -s, --limiting_separation
The maximum distance allowed for stars to be blended in degrees
Default: 0.04
